$250k ~= £200k which gets you a decent lifestyle in London but definitely not living like a prince!
Yet with that salary you can afford a very nice house outside of central London, you can travel, eat at a fancy restaurant whenever you want, get the latest iDevice every year and buy a new car with cash when the old one breaks, provided you're smart with your money. To my European tastes that's living like a prince (not a king)
In the UK £200k puts you solidly in the 1% bracket - that is, 99% of people earn less than you. If that's not princely, I don't know what is.
It does not do anything for me: if I have to live in an apartment instead of a house I am not going to feel happy about it because 99% of people live in even worse apartment.
