It might on some, but for the most of us we are going to continue eating the same amount of meat as before. I visit the organic store to avoid GMO's and hormones in what I eat. I often see free-range eggs there as well. But I make about $20,000 a year (USMC infantry) and I can't afford to go there most of the time.

The free market solution to this is that you have to make the price differences close to non-existent between let's say free range eggs and normal eggs. Of course people dislike it when these things are put into light, and if they see that they can get free-range eggs for maybe 50 cents more instead of 2x the price, they would more than likely get the free range. The free market would then dictate that in order to compete, everyone needs to move to free-range because consumers want that product over the other.

So basically what I'm saying is that if you want real change, find a way to make the final free-range product cost-effective enough to compete within the same price range as normal products. Appealing to people to become vegans is not going to work on a large enough scale to stop this stuff.
