Heard a guy on the radio promoting what he described as an "understandable" way to talk about wages and prices worldwide. He suggested using a Big Mac as the standard. And the cost would be expressed in how long, in minutes, the typical worker in that location would have to work to pay for a Big Mac bought in that location. I saw online that the national average price of a Big Mac is $4.99. At $7.25 minimum wage, that means 41 minutes of work to pay for the Big Mac (assuming my math is right, which may be a false assumption.)
