part of this was/is cultural to jew people
the "is" in your statement pretty much proved you're a bigot. even if the rest of the post might be historically accurate, that one word revealed your racist intentions pretty clearly. your description pretty much described ALL immigrants who move here. except jews havent been immigrants for the better part of a century.
and as for your claim to be helping minorities by pointing this out, it looks like we've been doing fairly well without your help thanks.
I understand you are a russian jew, I am learning more about your people everyday, I understand where your anger comes from but I am learning how to deal with that kind of behaviour without responding in a rude or uncivil way.
Part of the cultural stereotypes about jews have to do with their culture. There is nothing racist about that, that is true of almost all cultural stereotypes.
Of course immigrants have traditionally had a harder time getting jobs in elite areas of the country. The exception i see is Silicon Valley where lots of foreigners seem to get ahead quickly.
