Actually the interesting parallels are in the striking similarity of values shared by the pre-war fascists and the modern corporadoes.

The Nazis were more extreme and systematic about pursuing their aims, and they did the militaristic jack boots and pantomime thing, which the corporadoes don't do to anything like the same extent.

But it's desperately naive to believe that just because there are no jack boots and sieg heil salutes the corporadoes aren't inherently fascist and totalitarian.

It may be a more a sophisticated form of fascism with more indirect violence and abuse. But for anyone who can be bothered to do some basic research, there are obvious similarities between the pre-war fascist doctrine of violence and war as inherently virtuous, and the corporado ethic of 'competition' as an unarguable social good.

Likewise with the explicit social Darwinism of the Nazis and the implied social Darwinism of the corporadoes, where individuals who cannot be forced into delivering value to the state must be punished - see e.g. the current Tory pogrom against those on disability benefits.

And so on.

I think it's more dangerous not to acknowledge the parallels, than it is to flee shrieking from them because they break some imaginary rule about Godwinism.
