There is obviously a strong correlation between education and family income. The higher the level of education the higher the level of family income. So the dubs also likely have the lowest family incomes in these countries, as they do in the US. As expected. So the Dark Lords may effectively keep the poor and stupid trapped, but they will continue to lose the smartest and most capable. And let's hope the Dark Lords can't continue to get blood out of these turnips.
The higher one's education attainment level, the less religious they tend to be.
There is also a correlation between intelligence and religiosity - of any kind. The higher one's IQ the less likely he or she is religious, and vice versa. There is a strong correlation between fundamentalist religionists and lower intelligence, in US studies. It is likely the same situations exist in these countries.
And before some of you theists whine, we have posted empirical, scientific data in support of the above statements many, many times. You too can Google scholar it.
There is also a strong correlation between stupid people and obesity. But I digress.
