There are other options:
1) Print more money. Inflation affects the rich more than the poor.
2) Stop pouring money into the pockets of defense contractors. The !@#$%@#$^ stupid "War on Terror" cost us $6T over 20 years. https://en.wikipedia.org/wiki/War_on_terror . To say nothing of all the other military money pits.
3) Stop supporting the needlessly costly US medical system - switch to single payer now. We spent about $4 T/year on a medical system that's less effective than countries spending half that per capita.
4) 100% tax on wealth over $100 million would raise $3T just from the 400 richest Americans - https://en.wikipedia.org/wiki/List_of_wealthiest_Americans_b... .
