Answer the question below in 400 wrds maximum. (only 1 paragrapph)

The Big Mac was used as a benchmark for comparing the cost of living and real wages around the world. You will need to do some research, but as of right now, which city/country has the highest cost of living compared to real wages? What does that mean for the standard of living in that country? How does that standard of living compare to the standard of living in California? Why is the cost of living so high in some places and much lower in others and how does the exchange rate reflect those regional differences?
