The Debt “Black Hole”: Why Easy Money Keeps Pulling the Economy In

In this episode of the Money Metals Midweek Memo, host Mike Maharrey leans on Greg Weldon’s “debt black hole” metaphor to explain how towering obligations now warp policy, markets, and household finances.

The lens is simple and unsettling: when the mass of debt grows large enough, it distorts everything around it, and escaping the pull requires doing more of what created it in the first place.

The Set-Up

Public debt eclipsed $38 trillion last month, rising 64.6% in just six years and arriving years ahead of the Congressional Budget Office’s 2020 projection that $37 trillion wouldn’t appear until 2030.

Washington still spent roughly $7 trillion in fiscal year 2025, a 4.1% increase from the prior year, with September alone registering $446 billion in outlays even as calendar effects made it the lightest month.

Against that scale, tariff math collapses. Fiscal 2025 brought in about $22 billion from tariffs, up 42% year over year, with September’s $30 billion reflecting the post–“Liberation Day” surge.

Even a generous annualized run-rate of $400–$500 billion barely covers one month of federal spending and could fade if “negotiated” deals lower rates. The deficit still ran about $1.8 trillion, and interest costs crossed $1 trillion, now the second-largest budget item.

Politics, Incentives, and Why Cuts Don’t Come

Maharrey notes that every president since Grover Cleveland has left office with more debt than he inherited. Incentives favor spending because programs buy votes while cuts assign blame.

Only about 27% of the budget is truly discretionary; the rest is bound up in mandatory programs and interest payments that are politically or mechanically difficult to trim. Tariff rebates sound appealing on social media, but the arithmetic shows they require more borrowing and serve mostly as theater.

The conclusion is blunt. You cannot solve a spending problem without cutting spending. Without confronting Social Security, Medicare, national defense, and the ever-rising interest tab, the gravitational mass of the debt black hole continues to increase, pulling policy choices along with it.
