In particular, you said that capitalism is not fascism. I agree if by capitalism you mean just free market. But then perfect free markets use to be a quite scarce commodity in world history.
I have already defined capitalism earlier in this thread, and don't feel the need to repeat myself. But the short version is that "capitalism" is not an "-ism" at all. That term was popularized by Karl Marx, and was meant to be derogatory and to equate the economic model that it represents to a religion. It was an effective smear that many people buy into even today. Words matter.
Capitalism, in an economic sense, is nothing but the sum total effects of the many 'natural' laws of economics that express themselves whenever a society is predominately left alone to exchange naturally; therefore it's not an "economic system" or even an ideology in any sense. This almost never happens in reality, but instead we have varying degrees of freedom in markets. There is no exception to this rule though; that in every market, the freer that it is, the more beneficial for the consumer. Free markets are not always beneficial for the producers, nor for governments that need to restrict freedom in order to extract tax revenue; but freedom is always and everywhere a net benefit for consumers.
I think that's a good definition of capitalism.
Would you care to answer why the term capitalism, in some minds, can be such an "effective smear?"
Well, I'll try; but to be honest I don't think that is possible without my ow biases entering into my language. And an objective answer cannot have bias...
I don't believe that Karl Marx intended the term to misrepresent the idea, it's just that humans have a tendency to group abstract concepts into classes that make them easier to compare to each other. Karl Marx's experiences, and most peoples', is with systems; i.e. hiarchial organizations, logical machines, governments, etc. By By defining an -ism, he's implying that there is a structure to it, and thus an authority in control. Further implying that the results of the kind of capitalism that he sees around himself (also in London during the Industrial Revolution) is a product of intentional design. That is the kind of capitalsim that people hate, the idea of some faceless elite is controlling the economy. The reality is that there is an elite that controls our economy, but they aren't faceless, they're elected to Congress; and they are all a far cry from "capitalists".
