It's definitely a class issue.
And lower class correlates with lower intelligence.
Guys with more money select attractive women as mates; women select tall, good-looking men with money as mates.
The poor often feed themselves with unhealthy foods causing obesity. This is compounded with the fact that,
they may well possess a metabolism adapted to places where food is a relative scarcity.
We're looking at a growing class divide:
On top there will be tall, rich and intelligent people;
on the bottom of the pyramid will be the trolls.
Now I think money correlates strongly with intelligence - up to a certain point.
I agree with the poster that said, and I'm paraphrasing,
"the elite of the super-intelligent people (160+ IQ) care more about expanding their knowledge of God(reality) more than material gain."
If that's the case, let's take for granted that they know what they're talking about and follow suit like good students.
