I thought it was well known that corruption is a bigger problem in developing nations which are likely to be considerably less capitalistic than first world nations?
In that sense, corruption is the process of a society developing towards capitalism, but using its pre-existing societal toolset of ad-hoc interpersonal arrangements, in all their messy complexity, rather than the established processes of societies with centuries-old institutional traditions of having 1 universal metric for everything (capital). As capitalism is based on inter-generational accumulation of wealth, corruption can only be resolved over generations as societies become more trusting of the rationalist paradigm.
