At some point, we can't keep borrowing to satisfy our debt(s). The question then becomes, what happens? This current inflation is actually a not bad thing for US debt, as we are inflating away some of it. It totally sucks for those of us that want to buy food and shelter though.
Either we endure some hardship(s) and have a miserable decade or three or we crash and burn.
I'm betting we endure the hardships. The other option(s) are much worse.
