I moved away from london, I'm lucky that I don't have family there or an emotional attachment to the city itself.
I feel bad for the others, I made an above average wage and chomped over 60% of my salary in rent (+20% in bills and taxes), even if I could have afforded to buy when moving there initially, the rate of incline was so great that after 1 year I was completely unable to buy a studio apartment.
Crazy.
There are even anecdotes about how "my home earns more than I do". :|
