NOTE: I do not mean to single any one person out with this reply. These sorts of notions (ie. poor people shouldn't own animals, people who feed xyz shouldn't own animals, breeders who don't perform every genetic test possible are irresponsible and shouldn't be allowed animals, etc) are deeply disturbing ideas to me personally, but seem to be more cultural (and really along sharp economic divides at that) than individual.
I fed my ACD Old Roy lamb and rice when we were going through a particularly tough financial spot. Lamb meal, then rice are the first two ingredients, which ended up actually being better than the first ingredients on her previously fed, more expensive food (chicken meal, yellow corn). She had better energy and poops on Old Roy lamb and rice compared to previously fed brands (and actually, she more recently did terribly on one of the expensive, grain-free foods..Taste of the Wild). I certainly wouldn't have appreciated someone telling me I have to hand over a then five year-old shelter dog who was adopted at age three and took years of intensive work to get her over several serious issues, and had bonded extremely closely to us and we to her because...we had to feed her comprably to how we ourselves had to eat at the time. We give our dog lots of exercise, training, affection, and stimulation. I have known plenty of people who keep their dog locked in crates designed to look like furniture and who pay for other people to interact with their animals. They did feed them expensive food though. Is food a good indicator of overall affection and husbandry in our society? Who would have actually taken our dog if she was to be removed from us for being fed Old Roy? She was due for euthanasia at the shelter...but maybe death would have been better than food of an inferior quality?
Not long after that was one of the larger dog food recalls. Expensive, even organic, foods were on that list. People who had previously declared on forums that, "not feeding your dogs these brands is animal cruelty"...were strangely silent after that.
I do hope to one day feed my animals (pets and meat animals) home-raised and prepared food, and I think if you are able to do that, that is just awesome. I'm not cool with maligning people based on economic realities and limitations.
