And that sort of thing is predictably wrong. It's premised on the combination of low interest rates and a lack of inflation, even though low interest rates generally cause inflation.

As soon as you get inflation, keeping interest rates low would make it worse, but raising them explodes the interest rate on the debt. And your other alternative to paying the high interest is to print the money to pay the debt, which also worsens inflation. So taking on that much debt is just a bomb that goes off as soon as inflation becomes non-trivial, and on top of that, is a thing that generally causes inflation.

To understand how people like that succeed, realize that there is always a market for someone who will tell you what you want to hear.
