It's really fun to go back through historical marginal tax rates (you'd have to adjust for inflation yourself in this link [1]) and see just how un-taxed the wealthy really are today. No wonder dynastic wealth is so prevalent. Tbh, I think we need more gradations and income above $1M should be taxed at rates in excess of 70%.
