Wealth Inequality
Distribution of net worth — typically more unequal than income
Wealth inequality is the unequal distribution of net worth (assets minus liabilities). Typically more unequal than income inequality. Wealth Gini: ~0.85 (US); income Gini: ~0.40. Top 1%: ~30%+ of US wealth. Bottom 50%: ~2%. Reasons. (1) Top earners save more; wealth compounds. (2) Asset prices rise (stocks, real estate). (3) Inheritance: passed across generations. (4) Lower-wealth families: more debt. Concerns: economic mobility, political power, social cohesion. Debate: causes, consequences, solutions (taxes, transfers, etc.).

Common misconceptions

- Just rich vs poor. Concentration at very top.
- Easily redistributed. Asset valuations, behavior changes.
- Tax solves it. Many factors; need multiple approaches.

Frequently asked questions
What's wealth inequality?
Unequal distribution of net worth (total assets minus total liabilities). Different from income inequality. Wealth: stock (cumulative). Income: flow (yearly earnings). Wealth more unequal than income because: (1) People save more from higher incomes. (2) Wealth compounds over time. (3) Inheritance. (4) Asset price increases. US: extreme by international standards.
How concentrated is wealth in US?
Highly. Top 1%: ~30%+ of total wealth. Top 10%: ~76%. Bottom 50%: ~2%. Federal Reserve Survey of Consumer Finances. Concentration rising since 1980s. Comparable to early 1900s levels (Gilded Age). Some other countries (Nordic): lower. Some emerging economies: higher. US position: among highest in developed world.
Why so much more than income?
Multiple reasons. (1) Compounding: wealth begets wealth (returns reinvested). (2) Inheritance: passed across generations. (3) Saving rates: high earners save more. Bottom 50% often have negative net worth (debt). (4) Asset prices: stocks, real estate rise. (5) Capital gains often taxed less than wages. (6) Financial sophistication: better investment access. (7) Tax laws favor wealth-holders.
What's the role of inheritance?
Major. Some estimates: 30-40% of US wealth from inheritance. Compounds over generations. Limits economic mobility. Different countries: vary in inheritance role. Estate tax in US: high threshold; little revenue (effective rate small). European countries: more substantial. Debate: should heritage be more taxed?
What about racial wealth gaps?
Stark in US. Median white family: ~$190,000 wealth. Median Black family: ~$24,000. Median Hispanic family: ~$36,000. Multiple causes. (1) Historical: slavery, redlining, discrimination. (2) Income differences. (3) Inheritance gaps. (4) Asset accumulation barriers. (5) Discrimination in lending, employment. Generational: hard to close. Major focus of policy debates.
What are policy responses?
Various. (1) Estate/inheritance tax: tax wealth at death. (2) Wealth tax: annual tax on wealth (proposed but not implemented in US; some other countries). (3) Capital gains: tax investment income similarly to wages. (4) Anti-discrimination enforcement. (5) Universal basic income. (6) Asset-building programs. (7) Education. Each approach: trade-offs. Highly political.
How does it affect society?
Multiple concerns. (1) Economic mobility: harder to climb when starting unequal. (2) Political power: wealth = political influence. (3) Social cohesion: greater divides. (4) Demand: wealthy save more; less aggregate demand. (5) Asset bubbles: wealth concentrated in assets. (6) Education inequality: wealthy can fund private school, etc. Various theories: productive vs concerning levels of inequality.
