I think you are misusing Berkson's Paradox here. It applies when you sample two extremes, i.e. when you look at the richest 0.1% and the most moral 0.1% and notice that the two appear mutually exclusive, even though they might actually be uncorrelated in the general population. When you look only at the richest 0.1% and notice their lack of morals compared to the general population, that is a legit correlation.
