As an outsider, the combination of this and the Republicans' contrived attempt to impeach Biden really serve to illustrate the knife-edge on which the US political system seems to have been built.
In countries that use a parliamentary system, the ability to get a budget through parliament is pretty much synonymous with executive power - a government that can't pass its budget resigns and then either somebody else attempts to form a government or, failing that, new elections are held. The US however operates a presidential system but leaves the budget to its parliament. That's an arrangement that can only be sustainable if the parliament is either under the control of politicians who are aligned with the president's agenda, or if there is a political culture and set of norms that values cooperation and the national interest over partisanship.
It's impressive that the US system has lasted as long as it has, but it's abundantly clear that the Republicans in Congress are no longer a party that can cooperate with their opponents in the national interest - those norms no longer exist, and they seem not to have existed for some time now. In such circumstances, I don't see how a presidential system can be sustainable in the long-term.
