Why the right is less evolved than the progressive left

The conservatives' problem is that they believe that the public good is a "socialist" lessening of freedom for the individual, a regression to a pre-individual rights collectivism (essentially medieval, but practiced in Communist countries [and fascist] in this century). The truth is that there is a HIGHER plane of the collective us, the public good, that is comprised of individuals with their full rights and creativity intact and even enhanced (in the case of minorities) working together for the common good. We're all in the same boat, not in separate boats fighting each other, dog-eat-dog. The right is less developed on the evolutionary chain than progressives. The progression (with each level including the former is dependence-independence-interdependece). The conservatives can't even SEE interdependence.
