I stumbled across
this article, and while I don't have much original to add, I find it rather interesting. I do know that some faiths admonish higher education so that may explain why Hindus and Reform Jews perform consistently well, while Jehovah's Witnesses and Pentecostals are in the bottom two in both categories.
From a
different article the following was written:
"Some of the income differences probably stem from culture. Some faiths place great importance on formal education. But the differences are also self-reinforcing. People who make more money can send their children to better schools, exacerbating the many advantages they have over poorer children. Round and round, the cycle goes. It won’t solve itself."
Do you believe this to be more of a contributing factor than anything else? It certainly seems to have a large affect in my eyes, but it may be overstated.
