Regional house prices are correlated with regional demand which correlate with regional job opportunities. I could go live in the sticks but then I'd struggle to find work. I moved to London because I couldn't find satisfying opportunities in the South East, 25 miles outside of London, let alone in the suburbs of Leeds. If I hadn't moved to London my 10 hour work day would have become 12-13 hours, including a nasty rush hour commute, and I would still have been paying £500/month in transport for the privilege
and a high rent.
The problem here is that salaries don't scale in a linear fashion with regional property prices. In places like London, where quality property supply is low, rents are set to the absolute maximum, while still filling tenancies, and salaries, just as else where, are set to the bare minimum to fulfill demand. The result is rent as a % of take-home is maximized.
There are only three solutions. Lower property prices and rents (more housing supply), higher salaries and/or a more regionally distributed job market.
Don't get me wrong, i'm not bitching. I'm comfortable. But when people hear what you earn, and you can see by the way they react that they think you're a rich git, they just don't see these realities.
