I don't think that tweaking taxes is going to solve much of USA's problems.
USA's problems are foundations in failure mode and lawlessness in law run amok.
You have no courts, no contracts, no credit or bond ratings, and no banks from what I see and then with that lost most of your tax base being people who produce your GDP.
Too much self harm overall.
Agreed we need to start fresh kick out everyone and startover. Too bad that will not happen untill america is destroyed by another country.
America already has been destroyed from within. US Police did most of that ongoing far as I know since 1960's.
