nagoma: It's only when you violate natural selection that a shoeless child grows up to be crowned as the leader. Selective deprevation has some implication of reduced fitness to survive and genetic weakness. This weakness ( technically incompetence) is obscured from the favored but incompetent specie, can be selected and transferred to the genum, the order and the phylum. A single persons genetic weakness can be transformed into severe deficiency for a nation and can make the difference between a nation's survival or it's destruction. This is just my theory.
