I think it's deeply ingrained in British culture, through its very much alive social class system. Precisely what Brits (seem to?) like about that qaint system is what makes it possible to maintain such a careless elite class that is not only not punished for creating extractive vehicles such as the City, but even praised and rewarded for it, through British identity politics. "Great" Britain, world power, A-rank capital, and so on.

Brits never saw a social revolution, and it shows.
