Dirk, the whole point is that saying, for ex. Jews are natural-born business genii
They're not, BUT due to a long history of engaging in finance, trade, etc which was for thousands of years guided by their own survival guide in foreign lands, it certainly isn't a stretch to say engaging business especially finance is deeply rooted in the Jewish community.
the Fed Board of Directors is mostly Jewish
Fed, 4/5 of the largest media conglomerates, half the Supreme Court, dozens of senators and Congressman with dual us Israeli citizenship, most execs of large banks, majority of Hollywood, etc etc despite being a tiny.fraction of the US population... Whether that's racist or not doesn't change the fact that it's true that Jews are overrepresented in media, government and finance.. You'd expect more Latinos and blacks or even Poles to occupy these positions since they make up an exponentially larger chunk of the population yet that's not the case.
Jews were overrepresented in areas, once again, in which it was felt that a shortage area existed,
No, they went into trades influenced by their religious teachings and environment namely their own community. There's a big demand for welders and truckers yet I don't see Jews overrepresented in the welding or trucking profession. That's becayse the Talmud considers that goy jobs which Jews shouldn't take.
