"We are free to believe that this is the century of authority, a century tending to the 'right,' a fascist century." -Benito Mussolini
Capitalism itself is the embodiment of the dog eat dog Nietzschesque doctrine of fascism, the two are inseparable. This is why the rest of the world calls the US idea of capitalism/libertarian right wing market anarchism "neo-liberals".
The whole concept has been hijacked by Ayn Randian cultist types which only comes from the 1950s in America.
Adam Smith for example was not a fascist, he would be a moderate socialist, most people nowadays do not even realize it was Karl Marx who coined the term Capitalism back in the mid 1800s.
A primer of sorts on The Theory of Moral Sentiments by Adam Smith:
Smith saw the task of political economy as the pursuit of "two distinct objects": "first, to provide a plentiful revenue or subsistence for the people, or more properly to enable them to provide such a revenue or subsistence for themselves; and second, to supply the state or commonwealth with a revenue sufficient for the public services". He defended such public services as free education and poverty relief, while demanding greater freedom for the indigent who receives support than the rather punitive Poor Laws of his day permitted. Beyond his attention to the components and responsibilities of a well-functioning market system (such as the role of accountability and trust), he was deeply concerned about the inequality and poverty that might remain in an otherwise successful market economy. Even in dealing with regulations that restrain the markets, Smith additionally acknowledged the importance of interventions on behalf of the poor and the underdogs of society. At one stage, he gives a formula of disarming simplicity: "When the regulation, therefore, is in favour of the workmen, it is always just and equitable; but it is sometimes otherwise when in favour of the masters." Smith was both a proponent of a plural institutional structure and a champion of social values that transcend the profit motive, in principle as well as in actual reach.
My message generally to so called "Libertarians" (neo-liberals) in the USA when they start to wake up from the folly of their views is "Do not fall for false revolutions" fascism can hide behind any face as it usually has the backing of the capitalist establishment to project itself however it likes. ("Fair and balanced" anyone?)
