I think one of the most interesting parallels between Nazism and Trump is that in the 1930's establishment conservatives in Germany viewed Hitler as a buffoon, but one they could control. They hated the liberals so much and were so afraid of them coming to power that they figured he was worth it.
Sounds awfully familiar.
There are two reasons I wouldn't want to push the parallels too far.
One is that history never really repeats itself, the conditions are always changing.
And the other is that I've known too many people (most of them now no longer with us) who were anticipating the 'new 1930s' (and the final showdown between socialism and barbarism, I guess a bit like that between neo and Agent Smith? ) since at least the late 1940s. They'd have loved Trump, to them he'd be a like a harbinger of the End Times and the inevitable socialist Rapture.
However, what you say does bring to mind the relationship between Trumpery and the Koch Brothers. I mean, they spent an ill-gotten fortune trying to create a movement to shift the political landscape in a callous mad-libertarian direction, and some of that probably helped produce Trumpery.
But when their ideology met reality, it's not so much that 'reality won', as that their ideology and reality shagged each other and produced a bastard chimera that doesn't look much like either of its parents.
It _is_ a little bit similar to the industrialists and aristocrats who thought they could use Hitler and got something that didn't go according to plan. It's different in that the Kochs never directly supported or funded Trump, indeed I think they never could stand him, they just inadvertently helped create the climate that produced him.
