Perhaps but the way a lot of British people view things is quite inverse to Americans: Instead of thinking of ourselves as "temporarily embarrassed millionaires" like a lot of Americans do, we think of ourselves as having "temporarily escaped poverty."

Meaning we view other countries through their most disadvantaged and genuinely believe that that could be us one day. If America treats their poorest badly, we believe they'd treat us badly if we ever had a bad run of luck.

The UK used to be a country of strong social safety nets, I'm not sure what it is today -- I don't recognise it (without getting overly political).
