Sure, Ashkenazi Jews have been shown to be prone to genetic diseases due to sticking too close to their gene pool. However, the impetus for marrying other Jewish families and thus having access to the family business required proving your business skills and proficiency in studying scripture. I guess people are pretty interested in the prominence of Ashkenazi Jewish physicists and mathematicians in the early 20th century. Albert Einstein? Niels Bohr? Edward Teller?
