Turns out that part of the difference can be explained by the effects of their religion on their ability to earn. Conservative Protestants:
- Are poorly educated. This is because their beliefs don't fit with mainstream education, and so they home school instead. They also 'follow advice from church leaders who discourage attendance at secular colleges and universities' (again, to stop their children from being exposed to alternative ideas).
- Have more children, and younger. Early reproduction further limits the opportunities for education and career development, and also means they have less to invest. Interestingly, wealth increases in families with one or two children (because it motivates people to invest for the future) but decreases with more.
- Have stay-at-home mums. They are more likely to be single-earner households, especially when the children are young.
So much for the fundamentalists. What about the rest of us? Well, compared with mainstream Protestants and Catholics, Jews accumulate wealth faster and end up richer. But people with other religion or with no religion (that's us Humanists!) well, they're about the same.
Religious leaders are fond of lecturing us on the perils of secularism - in particular that it brings with it materialism and selfish greed. This study is yet more evidence that they're wrong. For better or worse, Humanists have similar material values to 'normal' Catholics and Protestants.
