Affiliate Marketing Secrets

To my knowledge, it’s Jews and Episcopalians… these two groups have the highest average education and highest average income in the United States.
But Jews are divided – the most liberal are called Reform, the most conservative are Orthodox, and those in the middle are called Conservative, while half of Jews are not religious and/or do not affiliate with any of these.
So which group of Jews is counted in the “highest average education & income” statistic? All ethnic Jews?
And how do these 4 groups of Jews compare in terms of education and income? (I would guess, from highest to lowest, the order would be:
unaffiliated/agnostic/atheist
Reform
Conservative
Orthodox
Is this correct?
Are these people’s high educational and career attainment due to something about their religions? If so, what? Or are they due to other factors? (Maybe high IQ in the case of Jews, and high class & IQ in the case of Episcopalians?)
Are there some other high-achieving religious groups? What about Unitarians? Presbyterians? Baha’i? Anyone know?
I’m assuming that Evangelicals, Baptists, Catholics and Muslims are all at the bottom… correct?
