All this debt has a permanent cost. If interest rates ever nudge back up past 3 percent, this year’s $6 trillion borrowing spree will cost $180 billion in additional interest costs every year, forever. That’s $180 billion annually that could otherwise provide tax relief, assist veterans, or improve infrastructure. Instead, it will pay interest to bond holders. What a waste of tax dollars.

This year’s Democratic spending binge is not the end of the story. Biden still has $3 trillion in leftover campaign promises covering Social Security, health care, higher education and other issues. If his entire agenda is enacted, the national debt held by the public — which was just under $17 trillion before the pandemic — would reach $44 trillion a decade from now.

The long-term danger is that today’s irresponsible government borrowing is set to collide with 74 million baby boomers retiring into Social Security and Medicare systems that are projected by the Congressional Budget Office to run a $112 trillion cash shortfall over the next three decades, including the resulting budget interest costs.
