What percentage of Europeans are actually descended from aristocrats though? I mean, I'm sure everyone has some noble blood buried somewhere deep in the family tree, but then as now, that alone doesn't make you an aristocrat. At the end of the day, we are all basically descended from peasants more or less and have to make our own way through life.
I think what's really at play here is that for a long time, ALL Europeans were effectively a privileged class ruling over masses of colonial subjects, and while that system has since been dismantled, that imperial mindset is still strong in many people's minds. There are countless people from Asia, Africa, and Latin America who have fully drunk the kool-aid and absolutely revere Western culture, values, and ideals, and want nothing more than to be a part of that society. And of course, rather than being hailed for their open-mindedness, these people are pretty much universally mocked from both sides for being clueless and naive.
