From Jeffrey A Tucker:
"Without the term fascism as an authentic descriptor, we have a problem. We have no accurate way to identify what is in fact the most politically successful movement of the 20th century. It is a movement that still exists today, because the conditions that gave rise to it are unchanged.
The whole burden of one of the most famous pro-freedom books of the century — Hayek’s The Road to Serfdom — was to warn that fascism was a more immediate and pressing danger to the developed world than Russian-style socialism. And this is for a reason: Hayek said that “brown” fascism did not represent a polar opposite of “red” socialism. In the interwar period, it was common to see both intellectuals and politicians move fluidly from one to the other.
“The rise of Fascism and Nazism was not a reaction against the socialist trends of the preceding period,” wrote Hayek, “but a necessary outcome of those tendencies.”
