Nothing could be more obvious with the revelations of science into genetics that people who are born equally worthy of human dignity and self respect are not born with equal capacities, My black neighbor, for example has two sons, one of which was poetry in motion in his athletic abilities and the other a Harvard graduated doctor who has SAT scores that were high seven hundreds. If one were interested in racial differences one could probably find the highest evils of intellectual capacity in a certain line of Jews.
I don't think, however, there is much difference in one person to the next in there potential to experience the joys of being alive free of the disease of self hate.
I would say, of hand, listening to the Trump collection of quotes, that he believes in his innate superiority precisely because of such self hate. Being joy is when the self isn't. Did you ever have an experience like laying on the grass and watching the clouds float by as a child? What amazing exceptional personal capacity did that take?
The need to compete and prove ones competence is a sure sign of insecurity as is Trump's German gene bull shit. How many German genes went extinct over that theory?
