That's not the reason IMO. It's because most of the super crook villains occupy the boomercuck generation and there's a generational divide where they're unable to pass on the torch to continue their legacy, or have nobody to pass it on to, or just don't care what happens after they're gone. Soros' son, for example, will probably not be nearly as effective of an evil cult of Judaism vampire as his forerunner no matter how hard he tries. Even though Jews have inherent criminal lying, thieving, stealing, and murdering genes, he's already unfathomably rich and has less motivation to get out of bed in the morning.
