A debt crisis like in eurozone countries in 2008 is very unlikely to happen in the US. For it to happen, it would require the fed working against the us government.
The Fed seems already constrained by the administration to not raise rates. Yields went up anyway. US primary deficit is huge and so debt to GDP is accelerating from different angles - interest, increased spending, increased yield demand based off uncontrolled inflation expectations etc.
In fact I suspect that the mega-pivot to AI is an attempt to solve the problem by massively inflating GDP, so that the debt doesn’t matter - ie radically grow the economy. It remains to be seen if it pays off and solves US’s problems.
At the end of the day, the US cannot escape from the forces that drowned Greece - inflation, investor confidence, debt spiral. It’s totally avoidable, but the US seems determined to race full speed ahead at it. Let’s see if Trump can play chicken with economics.
I think that it's more likely that many of them just like their jobs, and Trump has a history of orchestrating primary challenges against people who disagree with them.
Now, one could additionally argue that this is only possible because of their frankly insane gerrymandering, and one would be correct, so maybe it is ultimately their fault.
