If you want to moralise, that's your trip, but borrowing power is an objective measure of your financial health.
The United States is not a person and you can't translate folk economics from your kitchen table to the nation.
That's what everyone says until the government defaults on its debt. The US is a special case because of our unique situation as the military superpower and reserve currency, but look at Argentina, Venezuela, and the UK for a counterpoint.
How do you imagine the US can default on its debt? It borrows in its own money.
I dunno, if you were willing to issue me unlimited borrowing i'm not sure i would care about repayment.
