+1Many people these days simply cannot afford to eat well. A person can fill their bellies easier and faster and most importantly, cheaper on crap that is mass produced.
It's been demonstrated that corn syrup not only makes a person crave what they are eating, but it causes a person to gain weight much more quickly. And corn syrup is a main ingredient in these low-cost, mass produced foods. IMHO, crap food that is very cheap to make is a much bigger culprit than simply saying "people are lazy".
Corn (and corn syrup) is the basis of damn near everything in the modern, low-cost, mass produced, processed-food-stuffs that make up the American diet. The severity of the economic crisis is significantly veiled by all of this inexpensive "food". But that's not the worst part. The worst part is that nearly all yellow corn is now genetically modified...and that is a whole other major can o' worms.
