Govt doesn’t get any money from the interest paid. The underlying asset can eventually be sent offshore, put in trust or whatever, and never be taxed.
No, I'm saying that they wouldn't bankrupt themselves. They would realize assets (or take income) to pay off the loan, and that's when they would get taxed. The story that rich people don't pay taxes because they just take out loans and never sell the assets doesn't make sense to me for that reason.
