Utopian ideals of capitalism, socialism, libertarianism, etc will never fully exist. That seems to be a given and acknowledged by everyone, regardless of ideology. My simple working definition of capitalism here would be a free market coupled with a respect for private property and personal freedoms. The idea that the US has lived under capitalism at any point in the last hundred years is ridiculous. The government has its thumb on the scale of every market, owns almost all of the infrastructure, and picks its winners in every industry.
