On this date in 1955, Ray Kroc starts the McDonald’s chain of fast food restaurants in Illinois.

On a related note, Detroit Mayor Kwame Kilpatrick is the latest political figure to float the idea of a “fast food tax,” the newest incarnation of the “sin” tax. The reasoning is that fast foods, which tend to be higher in fat and cholesterol than other types of food, are unhealthy, and therefore worthy of special government attention.

The Detroit Free Press editorial page goes Kilpatrick one better, however, suggesting that the government “tax take-out food statewide — but by calories, not cost.”

Now of course the Christian tradition views gluttony as a sin. But as Thomas Aquinas writes, “Gluttony denotes, not any desire of eating and drinking, but an inordinate desire.” And in this case, it is worth asking which is more gluttonous: the fast food consumer who orders bo meal, or the State which constantly seeks new ways to feed its ever-voracious appetite.
