I'd say either you live somewhere where ALL those things are really cheap, or you don't know what it's like to be poor. I do well enough for myself and there are items in your list I wouldn't eat regularly even if I wanted, on price alone. Lamb and Venison are good examples, as are some fish despite the fact I live on the ocean. And Beef and Pork (I don't get this one) prices have skyrocketed of late around here.
