Combine this with property prices and I'm actually willing to believe the £500,000 figure isn't far off to have the same life as their parents generation have been able to achieve, but alas I grew up poor and I don't subscribe to needing any of this sillyness.
You can live much cheaper - I've seen 11k claimed by someone who shared a tiny basement and cooked all their own meals off the cheapest supermarket food - but you're making significant lifestyle compromises.
Maybe I'm more frugal than I realise.
Do you get any meals subsidised from your university, and do you actually have some savings while being able to eat out or get drinks at least once or twice a month?
I don't have any meals subsidised, and I do have savings -- about £3k/year. I eat out twice per week, and I get drinks more often than not -- although I do often get drinks quite cheaply, because I'm friends with some brewers.
On a salary of £20,000 a single person living in SE1 would be entitled to £58 a week housing benefit.

(Hasn't really gone up from the £525 it was in 1999 because my landpeople like an easy life and I'm no trouble.)
