> We are social animals who evolved in small communities

I agree with you. First, historically speaking, large disparities have led to revolutions and countless atrocities. Also our neural cortex isn't so highly evolved that it doesn't bow to the will of our chimp brain most of the time anyway, which is just to say we have a plethora of evolved intuitions and feelings. However, just because we have some innate biological sense of right or wrong or good or bad, that doesn't necessarily mean we should advocate for that in a normative way.

That was kind of my point. If we are going to build a better society I think it is important what normative values we strive for since we are not completely controlled by our impulses and those values will certainly have an effect on the systems we design and the relative effectiveness or lack thereof.
