> Do you expect your £18Kpa hairdresser (or the minimum-wage junior that sweeps up the hair) to spend £5Kpa (after tax) getting to work, or would you prefer to have go to Northampton every couple of months to get your hair cut?
I'd expect the price of the service they are providing to rise until it justified either them commuting into the city or their living in the city. If development in the city is constrained, probably the former.
