Steve, in post 49, hit the nail on the head regarding how I view this stuff.
Are you able to run a test where one group A is capitalist within its own group, but steals from group B and retaliates against group B attacks... and group B is capitalist within its own group, gets retaliated against when it attacks group A, and allows group A to steal from them without a retaliating?Again, I would defer to what Steve said but I'll address the last question. Politics is such an underhanded, Alice-in-Wonderland enterprise. Capitalists don't fight because it doesn't pay. The reason that it appears as if capitalists fight is because crony capitalists (i.e., non-capitalists) have the public tricked into believing lies. Take Warren Buffett. If you took a poll, then almost everyone would answer that he's a capitalist. But you have to be careful about calling someone a capitalist in Rand's sense of the term. In Buffett's case, he gets special deals from the current administrators of government and then goes on a return-the-favor campaign for them -- involving distorted nonsense about tax rates for the really rich.
Does such a relationship as I described in the above paragraph exist today between subgroups of humans?
Now, get this. Buffett says the super-rich should pay really high income tax rates, but what is the real story? The real story is that people as rich as him either don't earn traditional income, or whatever traditional income they earn can be dealt with in tax-avoiding ways. So the real story is that if top marginal tax rates were 39% -- or even if they were 99%! -- then Buffett would still be fine. So, knowing that high income tax rates don't hurt Buffett, we can ask:
What effect do they actually have in reality (who do they hurt)?
They hurt small businesses. In fact, high income tax rates are de facto "protectionism" for Big Business. This is like the story about established newspapers pulling up the ladder (to the top) in Capitalism: The Unknown Ideal. If top income tax rates are high, then small businesses who cannot afford to divert their profits around those taxes will be held down.
Small businesses will no longer be able to uproot Big Business.
There will be no more "creative destruction" (Schumpeter's description of capitalism). Instead of capitalism, there will be a few Big Businesses in bed with the government and working to increase the taxes and the multiply the regulations in the world. This is because they already have the excess funds to adapt to increased taxes and regulation -- but upstarts won't already have the same excess of funds. They purposefully "unlevel" the playing field. These people are they same kinds of people that get us into wars -- and again, lying to the public about what the wars are really about.
They call themselves capitalists. If you want to find the devil, then look first in the church. The very same people that tell you they want these high tax rates and tons of regulations in order to help the "little guy" are the ones profiteering off of the closed-off, monopolized markets created by nothing other than those very same high tax rates and those very same tons of regulations. These people claim to be the champion of the little guy, all the while holding him down in the depths of poverty and back-breaking toil.
There is a very good reason why Chinese politicians tend to retire as billionaires (and that something like 40 out of the top 100 richest people in the world are nothing other than non-value-producing Chinese politicians).
