The use of the word “infiltrated” seems to suggest a previously pure state that has been sullied. That seems unlikely, and it seems more likely that this is just a public realization that the project of democracy hasn’t made it as far away from brutal feudalism as we’d hoped. I doubt the line between the corrupting and the corrupted is very bright. Certainly the line between the lobbied and the lobby aren’t, or corporate leaders and elected ones. One would hope that the government at the very least is in concept different for having built in accountability and transparency, but once corrupt (or having always been less un-corrupted than what we’d hoped) the laws that set these conditions can be dismantled or sabotaged from the inside.
