From what I've seen, most simply don't have the desire to eat well, nor learn how to do so affordably. Sure, they cannot eat grass-fed beef with sweet potatoes, wild mushrooms, and asparagus, but they can eat rice, microwaved green peas and a couple eggs with hot sauce, and still have a nutritionally complete meal. Cheaper and faster than any fastfood. McDonald's arguably tastes better, though.

Nope. You can eat healthy even if you're poor; it's just more boring and repetitive. Most of what I know about nutrition and cooking I learned in high school, which was a) long ago and b) nothing fancy by American standards. I make a fuss about this stuff because I've got a lot of experience of being poor and I'm keenly aware of the tricky challenges of making food choices when you have very little money.

I'd ask for a refund on that snide tone if I were you, it's not helping your argument.
