No, in many regards they have to pay more. Transport costs in central London for these jobs, houses prices, dress codes for such jobs. Jobs that often are long hours so you have to have child care and other such costs.
poeple on low pay have to pay that, if both parents work, high income earns can afford for the wife not to work.
So people with low incomes dont have to pay for transport costs, they get it free?
the whole system is bottom heavy.
