Overview of Wealth Inequality and Why It Matters

Those who possess wealth can more easily move up the Maslow hierarchy of needs (see previous topic on Maslow in Happiness.) A certain level of wealth can be required to attain specific stages in Maslow’s hierarchy, particularly the stage of "Self-Actualization." People with more wealth have a greater potential to control situations. In other words, those with wealth can dictate the allocation of resources. A future example will be how Talyor Swift Changed the Music Industry.

Income and Wealth are related but not the same. Income is a flow concept and wealth is a static (snapshot). Recall Income (I) minus Expenses (E)  = Savings (S). Wealth is the sum of savings and negative savings can be a drawdown of wealth and become income.

Much of the following is AI generated by asking the question “What economic theories explain wealth inequality?”

Several economic theories attempt to explain wealth inequality, focusing on factors like capital accumulation, labor dynamics, taxation, and institutional structures. Here are some of the most influential theories:

1. Classical Economic Theories

• Kuznets Curve – Economist Simon Kuznets proposed that inequality initially rises as economies develop but declines in later stages due to redistribution and social policies. However, modern data suggests inequality has continued to rise in many advanced economies, challenging this theory.
• Ricardian & Marxist Theories – Classical economists like David Ricardo and Karl Marx argued that wealth inequality stems from capital ownership. Marx believed that capitalists accumulate wealth at the expense of workers, leading to increasing inequality.

2. Modern Theories of Wealth Inequality

• Piketty’s r > g Theory – Economist Thomas Piketty argues that when the rate of return on capital (r) exceeds economic growth (g), wealth concentrates among the rich, leading to persistent inequality. (discussed in more detail in a future post),
• Pareto Distribution – This statistical model suggests that wealth follows a power-law distribution, meaning a small percentage of people control a disproportionate amount of wealth.
• Superstar Economy Theory – Some economists argue that globalization and technology have created “superstar” earners, where a few individuals (CEOs, entrepreneurs, athletes) accumulate vast wealth due to network effects and winner-takes-all markets.

3. Institutional & Policy-Based Theories

• Rent-Seeking & Crony Capitalism – Some studies suggest that wealth inequality is driven by political connections, where billionaires gain wealth through favorable policies, monopolies, and tax loopholes rather than innovation or productivity.
• Taxation & Redistribution – Progressive taxation and social policies can reduce inequality, but weak enforcement or tax havens allow the wealthy to preserve their fortunes.
• Financialization & Asset Inflation – The rise of financial markets has led to wealth accumulation through stocks, real estate, and speculative investments, benefiting those who already own assets.

4. Emerging Theories & Challenges

• Declining Wage Share – Studies show that the bottom 90% of workers receive a shrinking share of national income, while the top 1% accumulates more wealth.
• Intergenerational Wealth Transfer – Wealth inequality persists because rich families pass down assets, reinforcing disparities across generations.

• Automation & AI – Some economists predict that automation will further concentrate wealth among those who own technology and capital.
• Income Distribution refers to how money earned (such as wages, salaries, dividends, interest, or rental income) is spread across a population.
• Wealth Distribution focuses on how assets (such as property, stocks, savings, and inherited wealth) are distributed among individuals or groups.

Income is flow-based—it represents earnings over time (e.g., annual salary). Wealth, on the other hand, is stock-based—it captures accumulated assets at a given point in time.

How Are They Related?

• Wealth often grows from income—people use income to buy assets, which then generate additional wealth (like investments in stocks or real estate).
• Wealth inequality can influence income inequality—those who have significant wealth can use their assets to generate passive income, widening the gap between rich and poor.
• Political & economic structures affect both—tax policies, financial markets, and inheritance laws shape how both income and wealth are distributed.
