I may be in a minority on this but I don’t see it so clearly that the fed govt will collapse anytime soon. It might but as long as people keep loaning it money it keeps getting the fuel to keep on.
Currently the government must borrow almost half of its operating revenue and over half of this borrowed money now is printed out of "thin air" by the Fed since the market for our bonds isn't like it used to be. So the Fed is now the one loaning the most money to the treasury. Something that would have been unheard of only a few short years ago.
Meanwhile the cost of running the government is rising exponentially. It's fate is sealed IMO, and it's just a matter of time now before a collapse occurs unless we can figure some other way out of this mess we're in.
