I half-remember from a sociology course years ago that studies of garbage showed that when the prices of meat and sugar are high, people waste more of it.
Do I remember right? Anyone know any theory why this is?
Wild ass guess:
Prices are high because of high demand.
Demand is high because people are using lots of the stuff.
Since a lot is in use, more is found in the garbage (and the same percentage is always wasted).
