1. Economic Inequality: The Rising Divide
Key Takeaways
- The "U-Shaped" Inequality Curve – Inequality was high in the 1920s, declined post-WWII due to progressive taxation and strong labor protections, but rose sharply post-1980 due to deregulation, tax cuts for the wealthy, and financialization.
- Stagnating Wages vs. Rising Corporate Profits – While productivity and corporate profits have increased dramatically, real median wages have barely grown since 1970.
- The Top 1% vs. The Bottom 50% – The top 1% now hold nearly 40% of national wealth, while the bottom 50% own less than 5%.
Historical Context & Trends
- 1920s-1930s: The Roaring Twenties saw extreme inequality, followed by the Great Depression, which led to New Deal reforms (Social Security, labor protections, high marginal tax rates) that reduced inequality.
- 1940s-1970s: Post-war prosperity, union strength, and progressive taxation led to broadly shared economic gains.
- 1980s-Present: Financial deregulation, the decline of unions, tax cuts, and automation have disproportionately benefited top earners, reversing mid-century progress.
Visual Representation and Analysis
- Income Inequality Over Time (1924-2024)Blue Line: Gini Coefficient (higher values indicate greater inequality).Red Line: Top 1% Wealth Share (%) over time.Key Insights:The Gini Coefficient (a measure of income inequality) followed a U-shape over the past century.In the 1920s, inequality was high, with the top 1% controlling over 40% of total wealth.Mid-20th century (1940s-1970s) saw a decline in inequality, thanks to progressive taxation, strong unions, and broad-based economic growth.Post-1980s, inequality surged again, driven by tax cuts for the wealthy, deregulation, and a shift toward financialized capitalism.By 2024, inequality is back near 1920s levels, with the top 1% holding nearly 40% of wealth, while the bottom 50% owns less than 5%.Key Drivers:Tax cuts for the rich. Declining union membership, weakening workers' bargaining power.Globalization and automation replacing mid-wage jobs.Financial market booms favoring asset owners.
Wealth Distribution Trends (1924-2024)
- Red Line: Top 1% Wealth Share (% of total wealth held by the top 1%).
- Blue Line: Bottom 50% Wealth Share (% of total wealth held by the bottom half of households).
- Key Insights:
- Income gains have been extremely unequal. The top 1% saw income grow 270% since 1924, while the bottom 50% saw only 28% growth.
- Median income growth has stagnated since 1980, while top earners have surged ahead.
- Middle-class wages rose consistently from the 1940s to 1970s, but post-1980 gains have gone almost entirely to the top 10%.
- Key Drivers:Decline in manufacturing jobs & rise of service-sector economy.High-income jobs in finance & tech pulling away from low/mid-wage jobs.Corporate stock buybacks & CEO compensation rising dramatically.
Union Membership vs. Wage Growth (1924-2024)
- Blue Line: Union Membership Rate (% of workers in unions), showing its decline over time.
- Green Line (Pre-1970): Strong wage growth, reinforced by a green dotted trendline showing a +1.26% annual growth rate.
- Red Line (Post-1970): Slower wage growth, with a red dotted trendline indicating a +0.48% annual growth rate.
- Black Vertical Line (1970): Clearly marks the turning point in wage growth slowdown.
- The visualization shows that as union membership declined, wage growth stagnated, suggesting a link between weakening labor unions and rising income inequality.
- Key Insights:
- Union membership peaked in the 1950s (35%) but has fallen below 10% today.
- The decline of unions coincides with wage stagnation for most workers.
- Unionized workers historically had better benefits, higher pay, and greater job security.
- Pre-1970: Strong real wage growth, aligned with rising union membership and economic expansion.
- Post-1970: Wage growth slowed dramatically, despite economic growth continuing—indicating weaker labor power and rising income inequality.
- By 2024: Real wages are only 10-15% higher than in 1970, despite massive increases in corporate profits and productivity.
- Key Drivers:
- Anti-union legislation (Taft-Hartley Act, "Right to Work" laws).
- Employer resistance to unionization.
- Globalization reducing high-wage manufacturing jobs.
Corporate Profits vs. Labor Share of GDP (1924-2024)
- Red Line: Corporate Profits as % of GDP (increasing over time).
- Blue Line: Labor Share of GDP (%) (declining as more income goes to corporations).
- Key Insights:
- Corporate profits as a share of GDP have soared since the 1980s, reaching over 14% in 2024, while labor's share of GDP has declined from ~60% to 42%.
- This means workers are receiving a smaller share of economic output, while corporations retain more profits.
- Key Drivers:
- Outsourcing & automation reducing labor costs.
- Weakened unionization reducing wage bargaining.
- Rise of monopolies and reduced competition.
Challenges and Pathways Forward
- Addressing Income Disparities: Ensuring that economic growth benefits all income groups, not just top earners.
- Rebalancing Labor and Capital: Strengthening worker protections while maintaining business competitiveness.
- Revisiting Taxation Policies: Examining how tax structures impact wealth accumulation and redistribution.
2. Social Mobility: The Decline of the American Dream
Key Takeaways
- Falling Absolute Mobility – In 1940, 90% of children earned more than their parents; by 1980, only ~50% do.
- The Role of Education & Homeownership – While college attainment has increased, the cost of education and barriers to homeownership have worsened wealth inequality.
- Persistent Racial & Gender Gaps – Black and Hispanic families face higher economic barriers, and while the gender pay gap has narrowed, women still earn ~82% of men’s wages.
