I think it's because intelligence doesn't help when it comes to earning money. The luck and social component is so strong that there is very little incentive for people to be intelligent.
I also do think that wealth inequality correlates with lower average IQ.
Rich people want to keep the majority of people dumb; breed them like cattle, hook them up to machines and milk them.
