It's not just that, its that Americans aren't eating real food anymore. When I was a kid my mom cooked dinner every night, went to the grocery store and came back with some lettuce, flour, spices, steak, etc. The problem is that people aren't actually cooking anymore, they're eating... Hell I don't even know what the stuff is. These things wouldn't be a problem if real food was available at a reasonable price and people actually got off their butt and cooked something edible.
