The capitalist system incentivises sociopathic and amoral behaviour. If you treat the people around you like mere tools for your own benefit you have a much easier time climbing the social/economic hierarchy. This means that psychopaths are disproportionally common in the upper strata of capitalist society. A psychopath would have no problem with abusing children for his or her own enjoyment.
Capitalism selects for dark triad traits. Organized pedophilia among the elites is a phenomenon particular to capitalism.
