  • [8th May 2026] The Hindu OpED: Openness, not isolation, is the bedrock of the West  

    PYQ Relevance[UPSC 2019] The long-sustained image of India as a leader of the oppressed and marginalised nations has disappeared on account of its new-found role in the emerging global order.” ElaborateLinkage: The PYQ examines changing global power structures, identity politics, and the transition from liberal globalisation to strategic geopolitics. It is directly linked with the article’s themes of civilisational politics, openness, democratic resilience, and global interdependence.

    Mentor’s Comment

    Major powers, especially the U.S., are increasingly viewing global politics through a “civilisational” lens. Recent statements linking migration, China, and geopolitics with the defence of “Western civilisation” mark a shift from the post-Cold War emphasis on openness and globalisation. The article argues that the West’s real strength came from openness to talent, innovation, migration, and diversity, not cultural isolation. This debate is important because it could shape future policies on immigration, technology, trade, and democracy.

    Why Is Civilisational Framing Re-emerging in Global Politics?

    1. Civilisational Narratives: Increasing references to “Western civilisation” by U.S. leaders frame geopolitics through cultural identity rather than institutional cooperation.
    2. Geopolitical Polarisation: Strategic competition with China, migration debates, and technological rivalry reinforce identity-based political discourse.
    3. Samuel Huntington’s Thesis: Revives the “Clash of Civilizations” framework proposed in the 1990s, which predicted cultural identities would dominate global conflicts.
    4. Identity Politics: Encourages viewing international relations through religion, ethnicity, and culture rather than shared economic interests.
    5. Policy Shift: Marks a contrast with the post-Cold War liberal order built on globalisation, open markets, and multilateralism.

    How Did Openness Become the Core Source of Western Strength?

    1. Institutional Adaptability: Western societies historically absorbed diversity and converted it into innovation through rules-based institutions.
    2. Migration Flows: Sustained economic growth through continuous inflows of skilled labour and human capital.
    3. Knowledge Networks: Facilitated collaboration among universities, firms, research laboratories, and international experts.
    4. Competitive Ecosystems: Enabled cross-border circulation of ideas, capital, and talent that accelerated innovation.
    5. Economic Dynamism: Post-Cold War prosperity depended heavily on openness to global markets, ideas, and demographic integration.

    Why Does the AI Revolution Reinforce the Importance of Global Openness?

    1. Artificial Intelligence Leadership: AI innovation increasingly depends on globally integrated talent pools and research ecosystems.
    2. Technology Ecosystems: Firms such as Microsoft, OpenAI, and NVIDIA rely on international expertise and cross-border collaboration.
    3. Talent Mobility: Global competition in AI is driven by the ability to attract the most capable researchers irrespective of origin.
    4. Innovation Networks: Breakthroughs emerge through multinational cooperation across research institutions and private firms.
    5. Strategic Competition: Countries restricting migration and academic openness risk losing technological leadership.

    What Did the COVID-19 Pandemic Reveal About Interdependence?

    1. Distributed Production Systems: Vaccine development relied on globally dispersed scientific and manufacturing networks.
    2. Collaborative Research: Moderna and AstraZeneca depended on international partnerships and global research ecosystems.
    3. India-UK Cooperation: The Serum Institute of India enabled large-scale vaccine manufacturing through international collaboration.
    4. Scientific Interdependence: Demonstrated that innovation ecosystems function through transnational cooperation rather than isolation.
    5. Supply Chain Integration: Highlighted the centrality of global production systems during crisis response.

    Why Is Immigration Becoming an Economic Necessity for Advanced Economies?

    1. Ageing Populations: Many advanced economies face demographic decline and shrinking workforces.
    2. Labour Market Requirements: Skilled migration supports productivity, fiscal stability, and innovation ecosystems.
    3. Human Capital: Immigration sustains entrepreneurship, scientific research, and high-technology sectors.
    4. Economic Competitiveness: Restrictive migration policies weaken long-term economic resilience.
    5. Fiscal Sustainability: Declining working-age populations increase pension and healthcare burdens without migration support.

    How Does Civilisational Framing Misdiagnose Modern Challenges?

    1. False Cultural Reductionism: Attributes national success primarily to cultural homogeneity rather than institutional effectiveness.
    2. Institutional Strength: Historical evidence shows adaptability and institutional resilience matter more than identity purity.
    3. Innovation Capacity: Open societies historically outperform closed societies in scientific and technological advancement.
    4. Policy Distortion: Excessive emphasis on identity politics can weaken democratic openness and global cooperation.
    5. Strategic Error: Isolationist approaches undermine competitiveness in interconnected sectors like AI, trade, and advanced manufacturing.

    Why Is Democratic Openness Central to 21st Century Governance?

    1. Global Challenges: Climate change, AI governance, and public health crises require transnational cooperation.
    2. Democratic Resilience: Successful democracies balance stability with institutional adaptability.
    3. Rule of Law: Open systems sustain accountability, innovation, and legitimacy.
    4. Institutional Trust: Democracies maintain strength by integrating diversity within constitutional frameworks.
    5. Strategic Confidence: Long-term resilience depends on confidence in openness rather than defensive isolationism.

    How Can States Balance Openness with Security Concerns?

    1. Regulated Immigration: Ensures lawful migration management while retaining economic benefits.
    2. Institutional Governance: Strong institutions prevent social fragmentation while sustaining openness.
    3. Strategic Integration: Balances national security with economic interconnectedness.
    4. Democratic Safeguards: Protects civic norms, accountability, and constitutional values.
    5. Resilient Globalisation: Encourages selective interdependence instead of complete decoupling.

    Conclusion

    The enduring strength of the West emerged from institutional openness, migration, innovation, and adaptability rather than cultural isolation. In an era of AI competition, geopolitical rivalry, and economic fragmentation, resilient democracies will depend more on openness with strong institutions than on narrow civilisational nationalism.

  • A key ocean current is collapsing. This could be devastating for the world and India 

    Why in the News?

    Recent scientific studies have warned that the Atlantic Meridional Overturning Circulation (AMOC), a major ocean current system regulating global climate, could weaken by nearly 59% by 2100 due to rapid Greenland ice melt and global warming. Scientists fear that crossing a critical tipping point may disrupt monsoons, intensify El Niño events, trigger extreme weather, and severely affect agriculture and water security, including in India.

    What is the Atlantic Meridional Overturning Circulation (AMOC)?

    The Atlantic Meridional Overturning Circulation (AMOC) is a vast system of ocean currents that acts as a “global conveyor belt,” circulating water, heat, and nutrients throughout the Atlantic Ocean. It is a critical component of the Earth’s climate system, responsible for transporting warm water from the tropics toward the North Atlantic and returning cold water southward at deeper levels.

    1. Ocean Conveyor Belt: Facilitates circulation of warm saline surface water from tropical regions toward Greenland and returns cold dense water through deep ocean currents.
    2. Thermohaline Circulation: Operates through differences in temperature and salinity that determine ocean water density.
    3. Climate Regulation: Transfers heat from equatorial regions toward higher latitudes, moderating Europe’s climate.
    4. Rainfall Influence: Shapes global precipitation belts, including monsoon systems across Asia and Africa.
    5. Carbon Regulation: Supports oceanic carbon absorption and heat storage, reducing atmospheric warming intensity.

    Why is AMOC Weakening Rapidly?

    1. Greenland Ice Melt: Accelerated melting releases massive freshwater volumes into the North Atlantic.
    2. Salinity Reduction: Freshwater dilution reduces ocean salinity and weakens density-driven sinking of cold water.
    3. Global Warming: Rising atmospheric temperatures increase polar ice loss and ocean heat accumulation.
    4. Circulation Slowdown: Reduced sinking weakens the entire overturning circulation mechanism.
    5. Observed Decline: Scientific studies estimate AMOC has already weakened significantly over the last 50 years.

    How Does AMOC Influence Global Climate Systems?

    1. Heat Redistribution: Transfers tropical heat toward northern latitudes and stabilizes regional climates.
    2. European Climate Stability: The northward transport of warm water acts as a “radiator,” keeping Europe, particularly Western Europe, considerably warmer than other regions at similar latitudes.
    3. Monsoon Regulation: Influences tropical rainfall patterns and seasonal wind circulation.
      1. By shifting heat between hemispheres, it helps define the location of the Intertropical Convergence Zone (ITCZ), a major rain belt. A weaker AMOC can disrupt this, leading to weakened monsoon systems and altered rainfall in Africa, Asia, and South America.
    4. Storm Dynamics: By transporting heat, the AMOC influences the intensity and path of storms and cyclones. It specifically contributes to the formation of the North Atlantic Oscillation (NAO). Changes in its strength can alter the frequency and track of storms across the North Atlantic
    5. Marine Ecosystems: The overturning circulation, which involves deep-sea sinking in the North Atlantic, helps circulate nutrients and oxygen throughout the ocean’s layers, supporting marine biodiversity.

    Why is the Collapse of AMOC Considered a Climate Tipping Point?

    The collapse of the Atlantic Meridional Overturning Circulation (AMOC) is considered a critical climate tipping point because it represents a “point of no return” where melting Arctic ice causes irreversible shutdown of vital ocean currents, triggering catastrophic, self-sustaining changes to global weather, sea levels, and ecosystems.

    1. Irreversibility Risk: Crossing a threshold may push the system into long-term collapse difficult to reverse.
    2. Abrupt Climate Shift: Climate systems may experience sudden disruptions rather than gradual warming patterns.
    3. Non-Linear Impact: Small increases in warming may trigger disproportionately large climatic consequences.
    4. Feedback Mechanisms: Ice melt and circulation slowdown reinforce each other, accelerating instability.
    5. Planetary Consequences: Impacts may extend simultaneously across rainfall, temperature, sea level, and ecosystems.

    How Could AMOC Collapse Affect India?

    1. The “Southern Pull” on Rain: As the Northern Hemisphere cools due to lack of heat transport, the Inter-Tropical Convergence Zone (ITCZ), the belt where monsoon rains form, shifts south. This moves the core rain clouds away from the Indian landmass, leading to the projected 10% to 30% drop in rainfall.
    2. Monsoon Instability: Beyond just “less rain,” the monsoon would become erratic
    3. Agricultural Stress: Irregular rainfall threatens crop productivity and food security.
    4. Extreme Weather: Intensifies droughts, floods, heatwaves, and erratic rainfall events.
    5. Water Insecurity: Alters river recharge patterns and groundwater availability.
    6. Livelihood Vulnerability: Threatens rural populations dependent on agriculture and climate-sensitive occupations.
    7. Disaster Frequency: Increases compound climate events such as simultaneous drought-flood cycles.

    What is the Connection Between AMOC and El Niño?

    The connection between the Atlantic Meridional Overturning Circulation (AMOC) and El Niño is a critical climate interlinkage where a disruption in one ocean basin triggers “chaos” in another.

    1. Climate Interlinkage: AMOC slowdown affects Pacific Ocean circulation patterns.
    2. Global Heat Imbalance: AMOC acts as a “conveyor belt” moving heat north. Its slowdown traps excess heat in the Southern Hemisphere while cooling the North Pacific. This disturbs the delicate temperature gradients that normally regulate El Niño-Southern Oscillation (ENSO) cycles.
      1. El Niño Intensification: Weak AMOC conditions may strengthen El Niño frequency and severity.
    3. Monsoon Suppression: Strong El Niño events historically weaken Indian monsoon rainfall.
    4. Global Weather Extremes: Intensifies droughts, storms, floods, and agricultural disruptions globally.
    5. Atmospheric Feedbacks: Alters temperature gradients and global wind circulation systems.

    What Could be the Global Consequences of AMOC Collapse?

    1. European Cooling: Northern Europe may experience severe winters despite global warming.
    2. Sea-Level Rise: Eastern coast of North America could face accelerated sea-level rise.
    3. Food System Stress: Agricultural productivity may decline due to rainfall instability.
    4. Climate Migration: Large populations may face displacement due to water and livelihood crises.
    5. Economic Disruption: Insurance losses, infrastructure damage, and supply chain instability may increase.
    6. Biodiversity Loss: Marine ecosystems dependent on nutrient circulation may weaken.

    What Measures are Necessary to Prevent or Mitigate the Crisis?

    1. Emission Reduction: Accelerates decarbonisation to limit global warming below critical thresholds.
    2. Climate Adaptation: Strengthens resilient agriculture, irrigation systems, and disaster preparedness.
    3. Polar Protection: Enhances international cooperation on Arctic and Greenland ice conservation.
    4. Scientific Monitoring: Expands ocean observation systems and climate modelling.
    5. Renewable Transition: Reduces dependence on fossil fuels and stabilizes long-term climate systems.
    6. Global Cooperation: Strengthens implementation of the Paris Agreement and climate finance commitments.

    Conclusion

    The weakening of AMOC highlights the growing fragility of Earth’s interconnected climate systems under anthropogenic warming. The issue extends beyond oceanography into food security, economic stability, disaster governance, and geopolitical security. For India, the risks are particularly significant because of the economy’s dependence on monsoon-driven agriculture and climate-sensitive livelihoods. Preventing irreversible tipping points requires rapid emission reduction, climate-resilient development, strengthened scientific monitoring, and coordinated global climate action.

  • “Medical negligence claims can be pursued against a deceased doctor’s heirs, says SC “

    Why in the News?

    The Supreme Court, in May 2025, ruled that medical negligence proceedings can continue even after the death of the accused doctor if the claim relates to financial loss recoverable from the doctor’s estate. The judgment creates a distinction between personal claims such as pain, suffering, or reputational damage, which extinguish upon death, and pecuniary claims, which survive against legal heirs to the extent of inherited property. The ruling is significant because it modifies the traditional common law principle “actio personalis moritur cum persona” and strengthens consumer rights in healthcare disputes. 

    What constitutional and legal principles govern medical negligence liability in India?

    1. Article 21: The Supreme Court of India interprets the right to life as including the right to health. This mandates that both public and private healthcare providers maintain standards that ensure accessible and accountable care.
    2. Consumer Protection Framework: Treats healthcare as a “service” under consumer law, enabling compensation claims.

    Legal Principles & Tests

    • The Bolam Test: This is the primary standard used by Indian courts. A doctor is not negligent if they acted in accordance with a practice accepted as proper by a responsible body of medical professionals, even if a different body of opinion exists.
    • Jacob Mathew Guidelines: To prevent the harassment of doctors, criminal prosecution for negligence requires a high degree of “gross” negligence. Police cannot arrest a doctor without an independent opinion from a competent medical board.
    • Res Ipsa Loquitur: Meaning “the thing speaks for itself,” this principle is used when the negligence is so obvious (e.g., leaving a surgical tool inside a patient) that the burden of proof shifts to the doctor to prove they were not negligent.
    • Tort Liability: Recognizes compensation for breach of duty causing injury or loss.

    How did the Supreme Court interpret survivability of medical negligence claims?

    1. Pecuniary Liability: Allows continuation of claims involving financial loss against the deceased doctor’s estate.
    2. Personal Claims: Extinguishes claims involving pain, suffering, defamation, or reputational injury upon death.
    3. Estate Accountability: Restricts liability only to the value of property inherited by legal heirs.
    4. Substantive Justice: Prevents procedural termination of compensation claims merely due to death of the accused.
    5. Consumer Protection Continuity: Ensures pending medical negligence complaints remain maintainable under law.

    Why did the Court revisit the common law doctrine “actio personalis moritur cum persona”?

    1. Traditional Principle: Held that personal legal actions die with the person.
    2. Indian Modification: Indian statutes progressively restricted the absolute application of the doctrine.
    3. Legal Representatives Suits Act, 1855: Permitted suits involving monetary losses against estates of deceased persons.
    4. Indian Succession Act, 1925: Section 306 preserved rights to prosecute or defend actions except in strictly personal injuries.
    5. Judicial Modernisation: Adapted colonial common law principles to contemporary consumer rights jurisprudence.

    What statutory provisions formed the basis of the judgment?

    1. Legal Representatives Suits Act, 1855
      1. Monetary Claims: Permits legal proceedings against legal representatives for financial loss caused by the deceased.
      2. Estate Limitation: Restricts recovery to inherited estate and not personal assets of heirs.
    2. Section 306 of Indian Succession Act, 1925
      1. Survival of Actions: Preserves rights to prosecute or defend legal proceedings after death.
      2. Exceptions Clause: Excludes defamation, assault, and purely personal injuries not causing death.
    3. Order XXII of Code of Civil Procedure (CPC)
      1. Substitution Mechanism: Enables replacement of deceased parties with legal representatives.
      2. Procedural Continuity: Prevents automatic abatement where right to sue survives.
    4. Consumer Protection Act
      1. Section 13(7): Applies CPC provisions regarding death of parties to consumer disputes.
      2. Consumer Rights Protection: Facilitates continuation of compensation claims in healthcare disputes.

    How does the judgment strengthen consumer rights in healthcare?

    1. Compensation Continuity: Ensures victims are not denied remedy due to death of the doctor.
    2. Institutional Accountability: Reinforces trust in civil compensation mechanisms.
    3. Access to Justice: Prevents procedural loopholes from defeating substantive claims.
    4. Victim-Centric Jurisprudence: Prioritizes restitution for financial injury suffered by patients.
    5. Legal Certainty: Clarifies ambiguity regarding maintainability of pending negligence claims.

    What concerns emerge from the judgment?

    1. Liability Uncertainty: Creates ambiguity where legal heirs inherit no estate.
    2. Enforcement Challenges: Complicates determination of extent of inherited assets.
    3. Defensive Medicine: May increase risk-averse medical practices in critical care.
    4. Litigation Expansion: Could increase long-pending compensation disputes against estates.
    5. Professional Anxiety: Raises concerns regarding prolonged legal exposure for medical practitioners and families.

    How does the judgment affect the healthcare ecosystem?

    1. Medical Governance: Strengthens accountability standards in healthcare delivery.
    2. Insurance Relevance: Increases importance of professional indemnity insurance for doctors.
    3. Hospital Liability: Encourages institutional compliance and risk-management systems.
    4. Patient Awareness: Expands understanding of legal remedies available in medical negligence.
    5. Judicial Oversight: Enhances role of courts in balancing professional autonomy with patient rights.

    Conclusion

    The judgment strengthens patient rights and accountability in healthcare by allowing pecuniary medical negligence claims to continue against a deceased doctor’s estate. It reflects the expanding scope of Article 21, consumer protection, and substantive justice in India’s healthcare governance framework.

    PYQ Relevance

    [UPSC 2024] In a crucial domain like the public healthcare system, the Indian State should play a vital role to contain the adverse impact of marketisation of the system. Suggest some measures through which the State can enhance the reach of public healthcare at the grassroots level.

    Linkage: The PYQ focuses on State accountability in ensuring accessible and ethical healthcare amid rising commercialization of the sector. The present judgment strengthens patient rights, consumer protection, and medical accountability, linking healthcare governance with Article 21 and professional ethics.

  • [7th May 2026] The Hindu OpED: Understanding inequality in India’s growth story  

    PYQ Relevance[UPSC 2017] What are the salient features of ‘inclusive growth’? Has India been experiencing such a growth process? Analyze and suggest measures for inclusive growth.Linkage: The article directly examines whether India’s post-reform growth has remained inclusive, especially amid widening urban-rural and class-based consumption inequality. It links strongly with GS-III themes of inclusive growth, welfare distribution, labour reforms, poverty, inequality measurement, and human development disparities.

    Mentor’s Comment

    India’s growth story is increasingly being questioned for its uneven distribution of gains. The assumption that inequality in India is moderate when compared globally is being challenged now. The Household Consumer Expenditure Survey (HCES) 2023-24 data states that inequality, especially in urban India and in non-food consumption, is far deeper than commonly estimated. While India has emerged as one of the fastest-growing economies, consumption patterns reveal widening disparities between rural and urban India, between rich and poor, and within social classes themselves. The top 10% in urban India account for 27% of total non-food expenditure, while the richest urban households spend nearly nine times more than the poorest rural households. 

    Why does measuring inequality in India remain methodologically complex?

    1. Multiple Dimensions: Inequality exists across income, wealth, consumption expenditure, and access to opportunities.
    2. Data Limitations: India lacks reliable and frequent income and wealth datasets. Consumption expenditure therefore becomes the primary proxy for measuring inequality.
    3. Methodological Changes: HCES 2023-24 introduced methodological modifications, making comparison with previous NSSO rounds difficult.
    4. Measurement Variations: World Bank estimates place India’s Gini coefficient at 0.25, while HCES-based estimates suggest a higher overall consumption inequality of 0.29.
    5. Sectoral Disaggregation: Urban inequality appears significantly higher once rural-urban and food-non-food distinctions are separately examined.
    6. Consumption Bias: Food expenditure shows lower inequality because food remains a basic necessity across classes.

    How does food and non-food expenditure reveal hidden inequality?

    1. Food Equality Effect: Food expenditure inequality remains relatively lower due to survival-driven consumption patterns.
    2. Non-Food Polarisation: Non-food expenditure shows significantly higher inequality in both urban and rural India.
    3. Urban Concentration: Urban non-food expenditure inequality is the highest among all categories.
    4. HCES Findings:
      1. Food expenditure Gini coefficient: approximately 0.25
      2. Non-food expenditure Gini coefficient: approximately 0.35-0.36
      3. Overall expenditure inequality: approximately 0.29
    5. Consumption Diversification: Richer households spend disproportionately on healthcare, education, digital services, transport, luxury goods, and recreation.
    6. Structural Indicator: Rising non-food inequality reflects unequal access to quality human development indicators.

    Why is urban India emerging as the epicentre of inequality?

    1. Growth Concentration: Most high-growth sectors are urban-centric, including finance, IT, services, logistics, and professional sectors.
    2. Urban Advantage: Mean urban expenditure exceeds the all-India average, while rural expenditure remains below it.
    3. Consumption Gap: Urban non-food Monthly Per Capita Expenditure (MPCE) stands at nearly 1.51 times the all-India average.
    4. Rural Lag: Rural non-food MPCE remains significantly lower at nearly 0.78 of the all-India average.
    5. Top-Decile Dominance: The richest 10% in urban India contribute nearly 27% of total non-food expenditure.
    6. Bottom-Decile Marginalisation: The same metric remains only around 4.5 times lower in rural India, indicating sharper urban inequality.
    7. Extreme Contrast: Mean MPCE of the richest urban decile is nearly nine times that of the poorest rural decile.
    8. Spatial Disparity: Urban prosperity increasingly coexists with informal labour vulnerability and rising living costs.

    How does class-based inequality deepen India’s growth paradox?

    1. Consumption-Based Class Divide: Inequality increasingly reflects divergence between spending classes rather than only interpersonal differences.
    2. Urban Professional Gains: Since the 1980s, urban owners, managers, and professionals have disproportionately benefited from economic growth.
    3. Stagnation of Informal Labour: Informal workers, agricultural labourers, and small farmers experienced comparatively limited gains.
    4. Class Inequality Persistence: Welfare expansion has not substantially reversed within-class inequality in urban India.
    5. Growth-Inequality Nexus: Economic liberalisation accelerated aggregate growth but also intensified concentration of gains.
    6. Non-Food Expenditure Concentration: Around 67% of non-food expenditure inequality arises from within-decile disparities.
    7. Food Expenditure Contribution: Nearly 33% of food expenditure inequality arises from within-decile disparities.
    8. Structural Dualism: India simultaneously experiences high-growth enclaves and low-income consumption traps.

    Why can lower inequality estimates produce misleading policy outcomes?

    1. Underestimation Risk: Consumption-based estimates may underestimate actual inequality because the richest households are often underrepresented in surveys.
    2. Policy Misalignment: Lower inequality estimates may weaken welfare urgency and social protection interventions.
    3. Welfare Retrenchment Concerns: Reduction in employment guarantees and labour protections could disproportionately affect informal workers.
    4. Poverty-Inequality Overlap:
      1. Around one-fourth of the richest 10% benefited from PMGKAY.
      2. Around 13% of them reportedly accessed BPL cards.
    5. Targeting Errors: Welfare leakages reveal institutional weaknesses in beneficiary identification.
    6. Social Stability Risks: Persistent inequality may intensify social fragmentation, urban distress, and political dissatisfaction.

    How does rural-urban disparity shape India’s development trajectory?

    1. Rural Consumption Constraint: Rural expenditure remains heavily food-oriented with limited discretionary spending.
    2. Urban Service Expansion: Urban economies benefit from greater access to finance, technology, education, and infrastructure.
    3. Human Capital Divide: Access to quality healthcare and education remains highly unequal across regions.
    4. Migration Pressures: Rural distress fuels migration toward cities without proportional employment generation.
    5. Regional Imbalance: Growth remains concentrated in select urban clusters and metropolitan regions.
    6. Development Asymmetry: Economic expansion has not ensured balanced regional transformation.

    Conclusion

    India’s growth story reflects a structural paradox where rapid economic expansion coexists with widening consumption inequality, especially in urban India and non-food expenditure. The findings from HCES 2023-24 indicate that economic gains remain concentrated among higher-income groups, while informal workers, rural households, and vulnerable classes continue to face limited upward mobility.
