Citation needed. Because in the US it’s considered some straight up age old bullshit that being rich makes you some kind of high minded philosopher smarter than the joe.

The US doesn’t really have a class system though — it has a middle class and an underclass. The fact that some middle class Americans are very wealthy doesn’t change the fact that they’re essentially middle class in behaviour and outlook.

The British, on the other hand, have a very complex class system and a meaningful upper class. I wouldn’t recommend trying to transport your understanding of “class” across the Atlantic.

The wikipedia page on the UK's class system says it is mostly wealth and education, but you make this case for behavior and outlook, which I'm guessing you really mean is ideological. But really would like some clarification.

I think you're talking about something entirely different.

The working, middle and upper class in the UK behave in very different ways, it's definitional. This article is the citation.

I would bear in mind that British class is quite different to American class. It's far less to do with money here.
