“When Ronald Reagan took office, affluent Americans paid a 70 percent tax rate on all income above $216,000. In the decades since, our country’s highest earners have seen their annual pay skyrocket, while the median household’s has barely budged. As a result, America’s 160,000 richest families now lay claim to 90 percent of its wealth. Studies suggest that this kind of inequality erodes social trust, abets plutocracy, and depresses economic growth. Politicians from both major parties routinely suggest that they see inequality as a major problem.”
Economic research and opinion polling suggest there’s nothing “extreme” about taxing incomes over $10 million at pre-Reagan rates.
