"Clarence Court still kill all the male chicks at birth though, there's no reason to think that Challens Chicks don't as well. Its still funding that industry and it's still exploitation for the sake of something perhaps tasty but entirely unnecessary."
Paperdoll the problem with that position is that you will never convert everyone to veganism. There are people who want to make some kind of difference by paying more for animal products in the hope that the animals will have better welfare. If you simply tell them "that's not enough" then it all gets a bit "well, what's the point then?"
DangerQuakeRhinoSnake totally agree that we should be all be paying more for, and eating less of, all animal products. That is the model that I believe we should be shooting for. If we all ate meat a few times a day (instead of every day, for both lunch and dinner, which many people do) then demand would go down. If we were also prepared to pay more for that meat, then I think we could reasonably expect that the animal product industries would have more opportunity to scale back, give the animals more time, more space, just generally better conditions.
That is what I think a realistic scenario would be.
