1. Slash trillions of dollars in annual federal spending to align with current tax revenues.

2. Raise trillions in additional tax revenue from the only entities able to pay more, corporations and the top 5%

3. Monetize the soaring federal debt by the central bank "printing money" and using this new money to buy Treasury bonds, as issuing new Treasury bonds for sale is the way the federal government funds its stupendous deficit spending.

One approach might be to do some of each, but there are political obstacles to any rational response to unsustainable federal debt expansion. Any cuts in spending large enough to be consequential will slash-and-burn either the cash overflowing in the federal trough that politically powerful cartels are gorging on, or entitlements that buy the complicity / passivity of the general populace. Neither is politically viable.
