Complexity isn't evil, but hiding in it some secondary interest of who sold that complexity likely is (because of Murphy's Law applied to human psychology?). Also it has a protective corollary: the interested parts in preserving complexity because injecting lets say a much needed and correct new simpler alternative would either reveal the aforementioned dubious interests or reduce the incumbent's authority (power), hence, all the incentives are set to boycott a system improvement from the top.
