No, they're right. The only saving grace is that it's not limited to the private sector; our political processes basically run on bribes, too, so they're just following our leaders' example. Just need to get bureaucracy in on the act, and we'll have the "Eastern Europe on the Eve of Collapse" trifecta.
I don’t think the problem is just easy corruptibility. Organisation leadership may have let this fester by not paying any thought towards aligning the incentives of their workers at every level and their own incentives correctly. Corruption is an easy explanation. But it’s probably just human nature to subvert and rebel.
