Why are Jewish people so disproportionately successful

My parents didn’t want me to marry my husband who isn’t Jewish…nothing to do with intelligence, but rather from history. Most of parents generation grew up with stories of the holocaust and the persecution of jews. Most of them faced anti semitism in their lives and my father feared it from my husband, he once, to my shock, said, “when you have a fight hell call you a dirty Jew”…we’ve been married over 40 years and he has called me many things …but never that :grinning::slight_smile: if you marry a Jew he felt I would be spared that. PS he adored my husband
