Taxing the rich is not going to solve any of this. It may help some, but it's nothing like the panacea certain people pretend it is.
If we took all the assets from all the billionaires in the US, that total is something like $6-7 trillion if we pretend there's no asset price decrease in the selling of said assets.
Sounds like a lot, but we're nearly $40 trillion in debt. Taxing the rich heavily won't solve a spending problem.
The federal government specifically, and the admin class in general was a lot smaller during our parents' era.
