someone states something like this (if you don't know they are reffering to the past then I inform you they did) - and I say it wasn't just plain simple jealousy of better-off people - Jews in pre-war Poland cooperated among themselves to oust non-Jewish competition - Poles were aware that the competition was not fair - this is my statement - I don't write of any further implications of these two things
OK. Jews were just better in business then Poles because often times they had to support themselves through centuries of migration by doing business. There was NO competition. Jews were better businessmen and often still are. I can say it because I have worked with both and Jews are probably twice as hardworking as Poles. Fact. So to say the least the envy was often unfounded.
C'mon, man. Anybody with something in common with anybody else has stuck together, for business and pleasure, for safety and convenience, since the beginning of time. There's business groups in every culture, some with religious overtones, like the Masons; and others secular, like the Elk's Lodge. There's literally thousands of these organizations, and they all work to promote business for their members in the respective fields. The Jews are no different. With people ostracizing them, if not outright persecuting them, what choice did they have but to band together, and watch each other's backs?
true. Every nationality behaves like that. See Scots, Irish, etc and many other groups eg. political groups in Poland at the moment.
