Every sovereign can print money and repay lenders, but doing so cause an inflationary cycle. When it looks like that is inevitable, borrowing rates start spiralling, so you have to print more money, and soon you are Zimbabwe.
Like the US is catastrophically indebted -- both parties have been negligent on this, though one party has been much, much worse than the other -- and right now there's a certain defeated malaise about 40T in debt. The last time bond rates were this high the country had only $6T in debt, and even that was considered a catastrophic level, and bond rate trends are...not looking good for those want government funds leftover after servicing the debt.
"Oh but we'll just grow the economy..."
The debt has grown by 6.5x, and the GDP has grown by 2.8x since 2002. The math just isn't mathing. And remember that bond prices were historically low, and if there was ever a time to pay down the debt....
Nope, $2T deficit, "hide in the ballroom bunker and hold the world hostage with the nuclear launch button" projects, and now a hilarious $1.3T bribe to voters. Utterly busted. It is astonishing that it took this long for the world's lenders to chuckle and say nah.
