Why aren't Jews more successful?

Can you cite any of this? Is it for Orthodox Jews? I am curious because it counters my observations.
I grew up/live in NY/NJ. My wife is Jewish. I have Jewish friends and friends with Jewish wives. I have observed the Intermarriage rate is higher for Women. I have observed non-orthodox Jewish women do quite well career wise. I would say a bit better than non-Jewish women would. I do see Orthodox Jewish women not doing as well with careers.
