Pew Research points out a correlation between income and education for both Jews and Hindus.
The more religious Jews aren't as well off financially as the more secular Jews, but still do quite well compared to the US population in general.
Here's a link:

If you download the PDF of the entire report, you'll see Jews broken out into two groups: conservative and reform.
It also depends on how you interpet the stats as to which group does better.
If you say that $75,000/year and above is doing well, then the Hindus win out. 65% of Hindus vs. 58% of Jews (conservative & reform combined) make over $75k/yr.
If you decide to focus on those who make over $100,000/yr, then Jews (once again including the higher-earning reform Jews) beat out the Hindus. 46% of Jews vs. 43% of Hindus make over $100k/yr.
The stats I enjoyed the most from Pew Research relate to JWs. JWs are almost at the bottom of the pile when it comes to education and income. But, they're #1 when it comes to adults who were raised in a religion and then left it.
