But that was my point. Even with the London loading of salaries, which is miles away from the SV salary differentials you see bandied around on here sometimes, the London absolute number is
usually smaller for most jobs. Banking is the one exception for some roles.
To invent some undoubtedly wrong numbers out of thin air: Earning £35k in Leeds or Manchester leaves a few hundred more to spend on luxuries and nights out than £50k working in a similar role in London. By the time you accounted for the huge extra expense on mortgage, season tickets to get to work, services and even ignore the price of a pint, you have less in absolute terms to spend than your "poor" Northern friend. I simply couldn't get it to add up the few times I tried. Now had the opportunity been to be a quant, I might have taken the opposite view... :)
I could have saved for deposit in the North, taken mortgage the day I moved there, accepted a markedly worse quality of life and lower money left after expenses for twenty years, to move elsewhere at the end with a nice nest egg. That's just a contributory pension with no tax relief.
