All of humanity would benefit from increased learned opportunities and more stimulating environments. This would produce a more egalitarian kind of society that would require far fewer centers of power and control compared to how the world has worked thus far. Those now in control are very protective of their presumed fiefdoms.
Egalitarianism is for socialists and only serves to bring the smartest and most talented down to a lower level. Better to cull the herd (through incentives to not procreate).
