I learned in a political science class in college that in the United States, through all means of production, it takes 5 kilocalories of gasoline to produce 1 kilocalorie of food.
I find it doubly interesting that our gasoline prices are so high, but the right is not objecting, b/c the additional cost per gallon is going to corporate interests and not to a tax, funding the state. The effect is still the same as if there were a sudden fifty cent a gallon increase in gasoline taxation. For the first time here in Louisville, I'm seeing super old super rich old ladies pumping their gas. Apparently, even they are avoiding the full service lanes because of the cost.
It is expensive!
