Capitalism can only exist within certain political frameworks so to distinguish it from a political system can create difficulties.
I do not think anyone would argue that governments cannot exploit resources-the vast bulk of the world's oil resources are under government control-although in the Middle East it can be argued as to which particular government controls the oil. The oil majors have had a declining share for decades.
The world economy may have doubled since 1990 but it has done nothing to protect the rust belt or many industrial workers in the UK. The trade partnerships that are being negotiated in complete secrecy would appear, from the little publicised details to, benefit the corporations solely.
The capitalist system may provide pension funds with cash for reinvestment but how many are signed up to private pensions today?
Social investment is an alien concept for the capitalist system and the continual flight to low cost production, taxation and regulation reduces the ability of government to fund pensions and welfare.
It is a flawed system and benefits a minority only. To me it appears that as the system grows more agile in preserving profit it will surely cause it's own downfall.
