I guess you've missed the KFC commercials in which the mother teaches her children that KFC makes better sense because to get the raw ingredients at the supermarket costs more. That commercial made me feel quite ill... I highly doubt that anyone is substituting an entire meal for 3 or 4 bags of chips. The concern is more that because they are working long hours and are poor, it's easier to just not cook and buy KFC every night, or cook something out of a box, such as a TV dinner, or 'instant' meals. Even the healthier of those are usually high in sodium and full of filler. A sedentary lifestyle is fine... if you don't eat too much. If you're sitting on your ass all day and not exercising much, you probably don't need 2,000 calories of chicken fat, high fructose corn syrup, and all the hydrogenated oils your heart can stand. I agree with you that the carrots would be the _better_ route to take, but the box of mac and cheese with gooey velveeta plasti-cheese is oh so much easier/better.
