Equality (of outcome) and Freedom can not coexist
Freedom and equality — two main pillars that we construct western society on. That is on the plane of ideas — in reality the two don’t mix very well.
Nature smiles at the union of freedom and equality in our utopias. For freedom and equality are sworn and everlasting enemies, and when one prevails the other dies. 
Whenever you give humans free reigns they will compete and co-operate to outdo each other. This will result in inequalities among a population. Is this not clear?
Still for some reason we demand equality for all — without naming what kind of equality, nor the costs it will have on society. A fully equal world seems to be an attempt to realize a dream that cannot be. For does this not ring true:
Even when repressed, inequality grows; only the man who is below the average in economic ability desires equality; those who are conscious of superior ability desire freedom; and in the end superior ability has its way. 
There will always be differences. The best way is to give people equality of opportunity (not equality of outcome) and then let society play itself out. Else, you lessen the individual’s freedom to act in the world — and diminish human potential.
