Fascism is, at heart, at least as much an economic system as it is a political one, and broadly, more so.
Fascism, alongside its political control of the populace, establishes economic control of the populace, and it does it very simply, by organizing the government to serve businesses and the wealthy few who control them, and by establishing a revolving door by which a relative few are allowed to freely move between control of the two.
This is the underlying point of Project 2025, and specifically the reason for the planned purge of civil servants. They are to be replaced by people who can be counted upon to serve the interests of the wealthy few and to deny the interests of the rest of the populace.
Again and again, our major institutions, from the media to the judiciary, have amplified Trump’s presence; again and again, we have failed to name the consequences. Fascism can be defeated, but not when we are on its side.
Those in power in those institutions, even if they don't share the political goals of Trump and his coattail-riders, are driven by their own greed to at the very least not stand too much in the way, since they too expect to profit.
Mmm... sort of.
In some very broad sense, yes, it's corruption.
In a narrower and more precise sense though, it isn't really, since "corruption" implies a violation of higher standards, which is what we've had, to a greater or lesser extent, pretty much throughout our history.
The difference in the coming era is that there will be no higher standards to corrupt. The things that were previously violations of higher standards will become the new standards. Theft and graft and cronyism will no longer be crimes or even (meaningfully recognized) wrongs - they will be the institutional norms.
And I don't mean this as mere pedantry - the point is that when what used to be corruption becomes the overt norms, things will get much, much worse than they ever were or could be when they were still corruption.
