Let's just stipulate everything you said is true. You do realize that the subordination of German corporations validates the quote you're ostensibly arguing against? Given your framing, German fascists would have loved the scale of cooperation that the American fascist executive branch is receiving from corporations, rather than have to do the difficult work of subordinating them.
The German population[1] was not unwilling; your error is not recognizing that it started with cooperation and grew until all of society was subordinated to the totalitarian state.
There was massive alignment across their society. What they “achieved” would not have been possible any other way.
As someone that abhors the destructive ideologies of that era — and has spent a considerable amount of time studying the history — it’s amusing ironic to be repeatedly compared to the predominant fascist ideology (not that you personally have done this) by people echoing the behavior of the predominate destructive left-wing ideology of the day.
From a historical perspective, it’s not the right-wing that I’m worried about now. I worry about the totalizing, agency-eroding, violence normalizing, and norm-enforcing (thought terminating) “ethics” that have taken firm hold of the left’s levers of power over the past 15 years.
[1] except for the German populations that they literally wanted to murder, of course.
