a method to evaluate the economic well-being of a country
- go to neighborhoods where BMWs are commonplace and look at the tires.
- If the tires on many of these cars are in good condition, the economy is pretty good.
- If they are worn, the economy is doing badly.
- Luxury car owners take care of their cars
- If times are tough, the tires are one of the first places they’ll skimp.
- If a whole bunch of BMWs are way down on treads, the economic situation is poor.
