Either: 1. They commute from cheaper accomodation outside of London. It's why the train services into stations like Fenchurch Street, Liverpool Street, Waterloo and Euston are so packed. Because it's cheaper to say, live in Southend and commute for an hour than to afford a place in the city centre. 2. They live with their parents, friends, other relatives or spouse, any of which either have better paying jobs or still own property from when it was cheaper to buy. 3. They share really cramped, sometimes illegal accomodation while sending a percentage of the money to their family abroad. 4. Their parents/family are rich and they're living on a trustfund of some kind. None of those are reasonable ways to live in London on average wages, but they are likely the reasons that your average developer/programmer job here is offering around 30-50,000 pounds a year, often nearer the low end.
