Well it's not really a "conspiracy" that Jews are one of if not the richest of the significant religious ideologies in America. Friends/family/mutual aid often goes along religious lines so it wouldn't be surprising to find out some of the investments look like a "jew-fest" as SBF is after all Jewish, and his family probably knows lots of Jewish people who happen to be about the richest families by religion in America on average.

If someone is a rich bad person, they are disproportionately likely to be Jewish. If they are a rich good person they are also disproportionately likely to be Jewish.... but some only see the bad.
