I think one interesting observation to make here is to think how one would group all these questions, into a meta question. What's the common thread among all these? As far as I can tell, it's 'why aren't things better?' The answer is simple: because you don't want it to be better, really. If you simplify the question down to 'why are Americans fat?', it'll become much clearer. We all already know the answer, most just want it to be some other, more pleasant explanation - hence never-ending fad diets. We want to believe, more than we want to face reality oftentimes :)
