Well, you could start by going after the billionaires who pay derisory amounts of tax. Trump is a standout, how much tax has he paid on his purported wealth of $5 billion? Or Murdoch?
That's probably a side issue. Where America has to increase expenditure is in re-inventing the manufacturing industries it exported to Asia, and refurbishing its decaying infrastructure. Both create jobs, and hence more revenue.
