Sorry - it is your premis that the purchasing power, when listed in the same currency, is at parity. And it is pretty obvious, if you had a clue. Based on salaries, my driver made $150 per month. So his apartment cost him 6% of his monthly salary. So, an for an equivalent amount of work, an equivalent apartment, at $500 per month, a driver here would have to be paid $8333 per month.
Clue to you -- Cost of Living and Purchasing Power Parity are two different things.
I thought it was obvious.
