Corruption is a pretty fuzzy concept, and most people aren't very good to handle gray areas. I think it's an issue of there not being incentives for any successful group to keep corruption as primary topic in the Overton window, since it's equivalent to marking yourself as an outsider to the political class. From time to time you'd have waves of populism that can be ridden, and outsiders can get in power, but those never really last. In my Eastern-European backwards nation that's affected by endemic corruption I was actually thinking of founding at one point a suicide-party, that is basically unelectable but who's main purpose would be to bring the necessary ideas in the Overton window, so that the successful parties at least have to address them. It's definitely not an easy problem, as most of those that actually understand social processes and can do something have mostly become wealthy and indifferent to the greater good.
