This is part of the reason the national debt keeps rising. During the 50 years after WWII the top marginal tax bracket never fell below 70 percent, twice what it is now. During those years we had a robust economy, the middle class thrived and we were paying down the national debt accumulated from WWII and the Great Depression. Inequality was not a thing.
