Well, Jews are smart – perhaps a master race – as @Robert Lindsay noted. However, though, the fact they own things – may not be due to IQ. I mean, family loaning, as I discussed in the above article – doesn’t need a high IQ. Basically, family members donate to a needy member – and then the member agrees to pay back with interest to the donators – all to make up for traditional bank loan rejection, something common with immigrants.
Anyway, though, it does seem like the groups doing family loaning have a high IQ anyway, including Jews, of course. Those groups would be Chinese, high-caste Indians, Koreans etc..
What about Somalis owning stores in the US?
