No the point is that PEOPLE will try to take advantage of tax codes regardless of the ideology presumably followed by the country. It has nothing to do with capitalism. You could undoubtedly find examples of elites avoiding taxes under feudalism, or in the theocracies of the world, in Communist nations, and capitalist ones.

The thing you ascribe to capitalism is a failure not of some ideology but a problem with human nature. If you blame capitalism and throw up your hands the problem can't be addressed.

Tax avoidance, and inequality generally, is not a distinguishing feature of US-style capitalism.

It appears to be baked into the cake of humanity.
