ristocracy was a term which meant ‘rule of the best’ and included a war-like class that felt it had certain duties to lesser individuals. In the European Middle-Ages like in China and Japan a system of honorable behavior and respect for women was included, reason for the rise of the Renaissance in Italy. Even the brutality of war did not prevent a resurgence of interest in the arts, literature and a code of conduct that allowed for a highly civilized layer of society.
Not so with the bourgeois commercial and industrial upper classes who feel no duty at all towards others nor a desire to follow certain rules of behavior. Their only interest is/was to control the production and exchange of goods and the control of money. Devoid then of a civilizational urge, they are as hard boiled and deprived of civilizing potential as the ever struggling lower classes (poverty does not breed nobility). Especially in the US where the economic mobility and capitalist-like competition make everyone uncertain in status, the upper classes have no civilizing character distinct from the proletariat (vide Trump).
