Statism; and socialism, corporatism, fascism are all variants of the same authoritarian dynamic, where the state exerts authority over individuals. The difference between socialism and fascism is, in terms of the principles involved, one of degree, not kind. I.e. You Do Not Own Your Own Life.
The cause to rally behind is, in general umbrella terms, freedom. The fight is against centralized power and the curtailment of individual rights. The facilitator of that power, right now in the US, is the Federal Reserve. Get the government and quasi-government entities out of trying to manipulate and manage currency and the economy, and the rest becomes just quibbling. I would love it if the fundamental debate nowadays was simply capitalism versus socialism, but the fact is there is no capitalism now. All we've got now is massive government intervention and manipulation of the economy, and whether the intervention favors the rich or the poor, at this point doesn't matter because they're running on fumes, over the edge of a cliff. Getting back to a real and healthy economy means breaking the government's power to distort markets, especially the currency. Once we get back to that point (if ever), then I'm happy to talk capitalism versus socialism, and what can we afford to allow the government to provide, etc. But until then, to me all forms of state interference in the economy are part of the problem, not the solution.
"The cause to rally behind is, in general umbrella terms, freedom. The fight is against centralized power and the curtailment of individual rights." This is where we are...People get so wrapped up in fight against this or that but we have to get to the point of it being about individual's freedoms . I highly suggest you watch the video in the last post.
