Boushey argues that inequality is not just unfair, but it is bad economics. She shows how rising inequality holds back growth by blocking talent, ideas and investments from reaching their full potential. When wealthy families dominate access to education and opportunity, it limits what the rest of society can contribute. Inequality also weakens competitions, undercuts public services, and distorts demand because when wages stagnate, people cannot spend, and the economy slows down. Her message is clear: reducing inequality is not a trade off with prosperity, it is how we unlock it. She lays out practical policies to fix this, from better wages and public investment to fairer taxes and stronger worker protections.
