Why are Americans incapable is seeing that Capitalism is evil?

Capitalism, and its advocates, have so far succeeded in producing a feasible myth that socialism is 'evil'. It is no surprise that it has worked so well, in fact, as it has managed to put all under the illusion that they can prosper and live a good life under capitalism - whilst some can, I admit, it's no fallacy to say that the majority of people in this world do not prosper, and it is only the rich oligarchs that continue to prosper and manipulate the hard-working people.
