Reagan busted an air traffic controllers' union and presided over reductions in the tax rate, cuts in social welfare programs, and the deregulation of industries like banking and natural gas. He also lifted ceilings on interest rates and price controls on airfares. Environmental protections were loosened.
Reagan easily won reelection and was generally considered a popular president. After a bout with high inflation early in his presidency, the economy rebounded.
Despite the positive economic data and landslide reelection victory, Reagan's economic legacy seems mixed. His policies contributed to high economic inequality, which arguably weakens the fabric of society. His decision to relax environmental policy also seems like a mistake, given what we now know about climate change. His tax cuts and related policies also contributed to a massive increase in the budget deficit and the national debt.
