I don't disagree. But to get that changed you'll have to do something about the food industry lobbyists who block any changes in policy.
I do not agree with those who spout off saying ban all prepared food. Many of these people do not have the skills to cook from scratch (I certainly wouldn't) and nationwide training is not feasible. That would be a multi-billion-dollar program in itself. Also, a fraction of recipients do have genuine medical or disability limitations that make this unrealistic.
Everyone should know how to cook a little. it isn’t that hard. If you can afford to eat out or buy prepared food for every meal that is your choice. My wife prefers to make most of our meals, although we could afford to eat out if we chose.
But if you are getting your food from your fellow citizens, it isn’t unfair to require that you learn to make macaroni and government cheese.
Those with disability limitations and the elderly already have an alternative in my area. It’s called Meals On Wheels.
