As I commented elsewhere, the Russian name for this is blat. It isn't just corruption. It is a personal trust network for getting things done, that you can't get done if you follow the official rules. You get what you need through corruption, and your ability to do so strengthens your trust in your personal network.
See https://www.youtube.com/watch?v=Zn86C4ZwBSg for an excellent explanation of it. And also an explanation of why the most important thing that Epstein did (the thing that actually made him most of it money), was run a blat network. Elites who had learned to trust that he could let them have otherwise impossible sexual experiences, were willing to pay him large amounts to broker introductions and financial deals that others couldn't.
