I was rather referring to the ones that have to live there, that make the city actually work as a functioning city. Earning **** wages and paying far too much for everything there, particularly rent.
Out of town tradesmen obvs charge more for going there to work; theres demand enough for Northerners to go there to do a job, charge double normal rates plus fuel and board while they work there; but I know who a few who've given up going there for jobs, just too much hassle, time away from home, and time lost travelling to even make it worth it for the London rates
