The old theory still works - print more money and borrow more money to keep the government rolling along.
This borrow more theory is heavily used in Canada too
That has been a general 'fix it' for a long time but not the only way to generate Federal debt.
Trump used the maneuver, cut taxes until the revenue stream was grossly insufficient. Evan with budget cutting, Federal debt occurred to cover necessities and the unexpected costs from a pandemic in the last 2 years of his administration.
Some think further budget cutting will solve the debt crisis in the face of an ongoing and expensive pandemic recovery.
Now Biden has to address Russian expansion, concerns over China and the Middle East.
That won't be inexpensive. But it's a necessity for maintaining national security.
As much as our elected officials have often been irresponsible, so has the general public in terms of consumer debt versus emergency and retirement savings.
Me.....I was taught to save for the future. And I did.
IMO, Social Security and many current social support mechanisms are at risk and likely won't last a decade.
At that time, few will argue about the debt crisis, more will simply want/need more and more support to survive.....a bit late to correct a debt problem effectively.
