I don't disagree with your first paragraph, but I don't think it contradicts the spirit of my original comment. Cheeses were invented because there was a demand for non-perishable protein. > And this isn't some new phenomenon, "cutting out work for wives and mothers trying to put food on the table every night" is an entire industry. Go look at any food ads from the 20th century. Sure, but that doesn't necessarily mean people's diets necessarily had to deteriorate. You get to pick 3 between healthy, convenient, cheap, and tasty, and Americans overwhelmingly chose the last three. This may caused some vicious cycles, but those are downstream affects caused by lack of demand.
