"First source I found shows FY2020 military budget is $714B, so cutting 25% would be $178.5B. I think that's a conservative number, considering that they may have gone over budget and it'll likely increase going forward.
A very simple look at wealth tax would be looking at total net worth of millionaires or billionaires in the US. Not able to find a distinct number for millionaires, but I see that the 660 billionaires in the US have a total wealth of $4.1T. 1% of that is $41B."
