That may be the case. May be. But what is definitely known is that avarice is baked into the Talmud, so much so that it's now b come part of the Jewish culture. To a point that if one leaves that faith, the avarice stays with him.

I have an uncle who claims to be agnostic now, but was raised Ashkenazi. He's one of the most shekel pinching and shekel seeking men I know. To the point that if he ever lends money to a family member, he demands a contract between the parties and will also assign interest to the debt.

Edit: now that I think on her physical features and look more closely, AOC does seem to have some physical traits of the Ashkenazi, namely the long face and huge teeth.
