Wall Street Journal reports today on a troubling, but altogether expected trend in spending and debt:

In the past decade, U.S. debt held by the public has risen to $15.9 trillion from $5.1 trillion, but financing all of that debt hasn’t been a problem. Low inflation and strong global demand for safe U.S. Treasury bonds held the government’s interest costs down.

That’s in the process of changing.

Interest rates are rising as inflation normalizes around the Federal Reserve’s 2% target. That and the sheer scale of debt being accumulated by the federal government has put the U.S. on a path of rising interest costs that in the years to come could crowd out other government spending priorities and rattle markets…

Along that path, the government is expected to pass the following milestones: It will spend more on interest than it spends on Medicaid in 2020; more in 2023 than it spends on national defense; and more in 2025 than it spends on all nondefense discretionary programs combined, from funding for national parks to scientific research, to health care and education, to the court system and infrastructure, according to the CBO.
