While I somewhat agree with this in theory, this is by far a new concept, and it has some problems. For one, companies have noted the desire for this and introduced their own "Organic" and "Grain fed" meat products to green wash the market. Meat that is legitimately not made in a cruel assembly line is both expensive and hard to come by. While it may be a possibility in New York City or LA, you just can't find it in a suburban Texas supermarket, not to mention you can't eat meat from restaurants. That's why it's easier for me to just cut meat from the diet instead of work my ass off to find certifiably "socially conscious" meat.
It's worth noting that many vegetarians argue that there's really no un-cruel way to raise an animal for meat. Even if they live on a happy magical farm, you still have to cut their head off at some point. Personally, I'm on the edge about this line of thinking. I think the difference between eating meat now and eating meat 1,000 years ago is that not only is meat is cruelly manufactured, but that our agricultural and culinary technology has evolved to where it's not necessary to kill animals to get the nutrition we need.
