| Here’s the issue. We don’t have any serious leaders on this issue. We don’t have scholarship divorced from politics about this issue. Maybe we never will. The Austrian school basically thinks this is the end of the world. The MMT folks think this is business as usual. The Keynesians are somewhere in the middle, but being in the middle of the road politically is not the same as an apolitical view on this. As a lay person who hasn’t studied economics enough to understand if this is an actual issue or a theoretical issue, I really need some politics-free scholarship on this. It doesn’t help that our political leaders say it’s an issue, unless it’s their party that wants that spending, then it’s fine. The right says it’s fine as long as it goes to endless wars, and the left says it’s fine when we spend the money on social programs. Both say it’s bad when the other side spends it, but not when their own spends it. This is exhausting and demonstrably not helping us resolve the fundamental issue of how do you manage a large society without it imploding. |
If lenders do nothing, then nothing really matters - keep borrowing and let your debt grow exponentially.
In practice though, lenders, in their wisdom or folly, get spooked when debt goes up. In the Greek debt crisis, it all started with debt in the region of 130% of GDP. Rolling the debt with more debt spiralled away as lenders wanted an ever higher interest.
So US would either need to start really inflating its debt and test the investors patience, print the cash and let inflation run away, or tax and cut spending.
In the first scenario it kind of doesn't matter where the limit is - people sometimes argue about magic levels. The issue is that eventually the debt grows exponentially, so once it's out of control, it will exceed any reasonable level pretty quickly.
Can the US convince the world that their debt is special? I'm not sure. My reading is that investors are already twitchy about US debt, for other reasons for now, but higher debt levels surely won't calm them down.
So really I think the US has no better choice than to keep its debt down.
