I'm missing information on what being a Jew in USSR entails so I concede that they may not have been part of the elite (I thought working for USSR propaganda machine would put you far ahead of the pack). I just thought being able to afford a commodore 64 back then already put you well ahead of the curve, in the 80s, but again this was after they arrived in the US, not much info on this.
Jews disproportionatily comprised the upper echelons of soviet politics, what do you mean?
