A good article. So far on earth no one has truly attempted to end "inequality" Your article is primarily about wealth disparity. Inequality is more about who dominates who, and who is exploited (usually Earth and minorities &/or women)

It is only very recently we even began to know that there is no "natural order, or chain of being" that dictated one over another.

It's a very new idea. Wealth has stayed with those in the ownership class, and we as Earth will only attempt to impact--not end-- inequality by valuing justice, (having very little to do with DNA, natural "fairness" and so on.)

I think you would enjoy more reading on sociobiology/ecopsychology
