I don’t believe there is organized corruption, and for the reason you have pointed out.
But corruption itself deals with dishonesty, deception, and falsely claiming qualities which you do not possess (fraudulence, which is included in the definition of conspiracy). And it is done by those in a position of power, and it correlated with financial outcomes (as you so elegantly stated in your reply here).
That is corruption. This is what I’ve been wrestling with the last few days. I agree it’s not highly organized, partly because that seems to require more coordination than the B12 seems good at doing, but also for my distaste for claiming ref corruption going back to learning sportsmanship in little league.
But if they are aware there is an issue, and those in power ignore it, allow it to continue, and even more, allow the financial rewards of failing to deal with it to accrue to them—is that not corruption? It fits, literally, the dictionary definition of it.
