I always wished the prison predecessor of “Fast Food Nation” had gotten the same traction, and maybe now, as a book, it will. Profit really is the toxic ingredient in the criminal “justice” system in this country — millions and millions disserved is the feature, not the bug. Even so, this exposé struck me as profoundly sad. A friend emailed the link with “dang, so much margarine,” which is ironic given that the gubmint, which sets the rules, is now cracking down on trans fats. My reaction: “Shit, so much diabetes.” Calories on these trays are as empty as the souls of those who come up with them. Although I do take tiny comfort in knowing most of the 1 percent have palates that never evolved to appreciate anything much more challenging. As I’ve often said, the tastes of Park Avenue gazillionaires and Death Row inmates are sadly similar.
