It was probably me.I'm not convinced that it's fair to compare national economics to family economics.
There are some enormous differences.
Families can be sued and compelled to pay. Nations are sovereign and can repudiate debt (once every few centuries, in practice).
Families do not set the value of the currency. Nations do.
That said, if I have a certain income (say $100,000/year for simplicity) and buy a house for $250,000, the bank will judge the risk involved and loan the money. If I repeat that process and buy 17 houses with the same income, the bank is probably not going to loan the money out of fear that they will not get their money back. Likewise, if the US GDP in FY 2022 was $23T. US debt is ~$31T. That is a pretty unhealthy number. At some point, maybe not today, maybe not tomorrow, but at some point, creditors are going to worry they won't get their principal back and interest rates are going to skyrocket to cover the risk. When that happens the $475B we spent last year to service already-contracted debt is going to mushroom. Like buying a house using an Adjustable Rate Mortgage right before you know interest rates are going to climb.
