It's marketing. MREs are not a long term survival strategy. It's beans, rice, dried peas and canned goods for us. Some spam, some tuna, stuff like that. I have a tiny farm with chickens, so we have eggs, lots of them, and access to chicken meat. I assume we would need some one on guard duty 24/7, probably 2 people. Growing your own food is exhausting and depending on if you have gasoline and tractors or tillers, your work load will grown proportionately to what you do not have. Yes, I do have a few bins of treats for baking now and then, (I have LP at my house, so for a while, we would have gas for cooking.) I think it would boil down to having a lot of the same old stuff that cooks up well in a dutch oven. Eggs and chicken while we have them. I can't justify the money on survival food. It may make a lot more sense in an urban setting where you don't have space, and have no ability to grow your own. I think it depends on what scenario you prepare for.
