I tread here very carefully, Politics in the US, has a very different split. Here in the UK, we have the left, split between centre left and communist, then the centrists, split between social democrats and social liberals, and the right, split between centre right, and far right, and whats called one nation conservatism, Then there are many shades in-between. However I think no matter the system or country, no system runs perfect capitalism as stated by Hayek "the invisible hand". In fact there are laws, regulations, controls, tax breaks, and good old fashioned nepotism, that skew the market. We need to be careful about skewing it so far its unjust. By the way I consider myself a social democrat. Hope that is not too contentious.
