Capitalism is the social form of nature. Survival of the fittest, protect you and yours, etc. People "not being dicks" goes against instinct, and goes against their self-interest. Why is it up to the successful to take care of the weak? If you really hate your situation, you can do something about it. You just may have to work harder than others. Life isn't fair and people aren't created equal.
As far as the tax system goes, I understand the argument of a flat tax. In fact, I agree with the basic philosophy. However, if you lowered the high bracket tax, you have to raise the lower tax bracket to break even. As a percentage of income, that puts a MUCH larger burden on the lower class. I agree with the poster who said lowering spending is the key. Less taxes = less tax burden.
Neoconservaticism and Reaganomics isn't the same thing as capitalism. It's actually closer to Corporatism, which was a basic philosophy of Mussolini's Italy. The problem is the fact that it was a gradual evolution in America, along with constant distractions, that the public didn't notice or care. The "trickle-down" philosophy of the 80s was a joke, and must have had politicians laughing at us. It did boost the aggregate economy, however income disparity and poverty skyrocketed.
Socialism or socialist policies are not the right answer, though. I feel like the biggest problem with the political culture in this country is the bipolarity of thought, the idea that there are only two possible answers. It's an ingrained idea of a our bipolar political system, although it leads to radicalism and hostility. There is never one answer, and there are never only two options. A compromise on middle-ground is usually the best route. Extreme changes are NEVER good for an economy. Ever.
Sorry for the rant. I'm in finals mode, I guess.
