Only a liberal thinks America has “classes”, caste system.
Paul Fussel, who was one of the Buckley/Gore supereducated mid-Atlantic types, claimed in his book Class that America did indeed have classes, which he proceeded to describe. In his telling, the "classes" were more like lifestyles. He personally aspired to die an "X" class member, an antinomian libertarian intellectual, free of the prejudices of his natal snobfest and the pretensions of the "high proles" (nouveaux riches still stamped with prole tastes and prole underwear) all alike.
Fussel might assign Trump to the "high proles", due to his love of flash and publicity and spectacularly built boats and women. A real upper-class type ("top-out-of-sight", because their houses can seldom be seen from the nearest public road) would incline toward 120-year-old wooden schooners, anoymously junky-looking cars, and the layered look.
