Also, there is exactly zero historical instance of hyperinflation caused by public debt labelled in a country's own currency. Zero.
There's little rational reasons to believe public debt will cause hyperinflation, and as I mentioned above there are in fact powerful effect acting in the opposite direction.
The only reason people make the link between those two is that hyperinflation is the canonical example of an economic catastrophe and because people believe debt to be immoral, it must lead to a catastrophe in the end. This is a religious/moral discourse, which has no link with the actual world.
And to conclude, keep in mind that high level of public debt is a political decision (borrow from the wealthy instead of taxing them) it would be quite straightforward to fix (with the 60s income tax level) but it's in the interest of no-one with a bit of political power.
For the record: most of inflation comes from rising costs in the supply chain (from supply issues, resources scarcity and/or wage raises). This is where we are now.
There exists instances of hyperinflation related to debt (Weimar republic's for instance) but this was due to debt labelled in a foreign currency (basically gold in this case).
The only two things that can actually make the system collapse in the next 30 years are:
- a communist revolution in the US (this is not happening anytime soon, do not worry).
- zealots with a debt fixation, who would rather collapse the entire economy because they think debt is immoral. This one is a little bit more likely, but given the strong ties between the financial sector and the political parties in the US, I really doubt these people would ever be in charge. Republican, when they don't control the White house, are prone to rant about how debt is unsustainable and should be reduced at all cost, but whenever there is a Republican president, the debt keeps rising.
