I will quibble and say not state capitalism, but corporatism. State capitalism implies de facto control of industry by the government, with business owners as vassals to political leaders. Corporatism is the other way around, and I think accurately describes the current political-economic system in the U.S. and U.K. The political leaders are vassals of the corporations. Libertarianism is taking that one step further and calling for eliminating government so that corporations can have direct and unimpeded rule.
