Interesting to compare the price of gas across political borders by equivalent purchasing power. For example Mexico and the US where gas is priced about the same generally speaking. A GS 12 federal agent earns $70000 annually and a Mexican federal agent earns $4500 annually gas is priced at roughly $4.00 along the northern states the after you factor out Litros vs US gallons.
The US agent earns 15.6x ($70k/$4.5k) more than the Mexican agent. That means at $4.00 per gallon the Mexican agent pays in time spent working $62.40 per gallon. That’s why the say Icarumba all the time
