Capital Gains Can Be Labor Income
Short summary
Economists Zwick and Zidar argue that labor's declining income share partly reflects how tax policy treats compensation structures—stock-based pay and pass-throughs are counted as capital gains rather than labor income. The research suggests policy design, not just market forces, determines how we classify work's economic contribution. For founders and high-earners, this distinction carries significant tax implications.
