Can't their success be more attributed to a culture that favors learning and education, as well as the relative financial prosperity of Ashkenazi Jews compared to other groups? That the children of successful artists, scientists, or financiers become successful artists, scientists and financiers themselves is least surprising.
I highly doubt it. For example in New York City there were historically immigrants from lots of different backgrounds all living in the same place working in the same industries. Is it just a coincidence that the most intelligent of them also became the most successful across every metric (on average)?
