"Owing to synthetic fertilizers and pesticides, genetic modification, and a conversion of farming from a naturally based to a highly mechanized production system, U.S. farmers now produce 3,900 calories per U.S. citizen, per day. That is twice what we need, and 700 calories a day more than they grew in 1980.
Commodity farmers can only survive by producing their maximum yields, so they do. And here is the shocking plot twist: as the farmers produced those extra calories, the food industry figured out how to get them into the bodies of people who didn't really want to eat 700 more calories a day. That is the well-oiled machine we call Late Capitalism."
