The flip side of the coin is how do rich people select accountants and wealth managers that they can trust? I have heard so many horror shows of celebrities getting ripped off by their accountants. It seems to happen even more to poor people who suddenly become rich - lottery winners seem unable to hang onto the cash. And the Murdaugh murder trial revealed networks of lawyers and fiduciaries playing fast and lose with client money (one example was a trust manager loaning Murdaugh huge amounts of cash from a trust for two minors who mom was killed in an accident, and the girls got a multi million judgement).
Are there trust networks? Or word of mouth and luck?
