Equality is made, just like inequality.
The place to start analysis is with real social relations, not idealized equality of capacities. If our discussion is to remain in the real world, rather than the traditional economic trick of supposing imaginary contexts for ideal-typical rational action, then let's begin with a concrete situation and a discussion of how we would fix the problem. My morals tell me that inequality is wrong and that striving for greater equality is the right thing to do. My morals and values are not subject to imaginary thought problems or scientific validation.
