Education is a multiplier, benefiting the high-IQ more than the low-IQ. Many citizens and an even larger fraction of policymakers wrongly think of education as an equalizer rather than a multiplier.
Capitalism and education benefit the lower IQ population far more than the higher IQ elite. It gives them access to a much higher standard of living than otherwise they could not do for themselves. We all live in dreams made real by a very small part of the population that is sustained by the rest once created.
I do agree about the equalizer and multiplier concept, but the better educated most often carry a far higher burden emotionally and financially.
