It will be “fixed” with tax increases. Absolutely no other solution is politically viable. Bend over and grab ‘em.
Two other solutions:
Print money to pay which may cause inflation
Sell assets to make payments.
Goverment land, oil/ mineral rights
Raising marginal rates will decrease or hold Federal revenues the same year over year. Always has. Lowering tax rates increases Federal revenue. Always has.
It was supposed to be fixed with the Dole tax increases in 86.
