- Less western support because of Trump
- No more trade deficiencies causes a lack of dollars in the world instead of letting it float freely ( and available)
Because of the dollar as reserve currency, the US can have debts without anyone protesting. But as soon as this advantage disappears, the debts become a problem => collapse?
If you need examples of how this plays out in the grand narrative(s) of finances, look at the top holders by country of US debt, the memes/arguments of the Fed's "money printer goes brrrrr", as well as possible geopolitical risks.
The end game is the federal debt has been inflated away, the dollar is much lower, and dollar denominated assets have been wiped out. So (if you think this is going to happen) get your investments into equity and the like and load up on dollar denominated debt that will also be wiped away.
Much of the population is paycheque-to-paycheque, so if we spent a year or two hyperinflating the currency, they might actually see a net win. They didn't have significant savings to go poof, but their $30k in credit cards, $50k car notes, $200k student loans, and $750k mortgages suddenly look trifling when you're shipping packages by stuffing them with crumpled million-dollar notes.
When the crisis ends, and we get the equivalent of the Rentenmark, they emerge with blank balance sheets and clean title on the assets they acquired before the crisis. It would be effectively a backdoor debt jubilee.
I can't imagine the domestic financial sector being too enthused.
