I like the Big Mac method to compare costs of living. The Economist ranks countries by how long you have to work to buy a Big Mac. That would make Mexico a very low wage country. AS for gasoline try going to a Pemex early in the morning. A Charanga ( POS) car will pull in and buy 20 pesos of fuel. That is less than 2 litres. That car will probably travel less than 10 miles on that fuel. Many families do not use the car except on Saturday to buy groceries and maybe Semana Santa. The cost of fuel does not affect the working poor but the high food prices make life very difficult. Do not believe the Mexican unemployment rate. Like most nations it is BS. Besides what good is that rate if you are counting some young kid working construction for 60 pesos a day.
