Thanks for the thoughtful response!
I actually think this paragraph you created is worth presenting and considering. The thing is, it’s pretty much been presented already. This is, for example, roughly the story of Bruce Friedrich (founder and CEO of GFI), and maybe pretty much GFI too. And that was my story too, and might be the story of a lot of EA animal/alt-pro advocates. So if this argument is presented, why not also consider its counterpart? (what I did)
I think this is subtly off. The story I’ve heard from alt-pro advocates is that we should focus on making it easier for people to drop factory farming because that would get people to do so, while generations of moral advocacy against factory farming have failed to achieve mass consumer change. That’s a historical argument about tractability—it’s not a speculative argument about how we might inspire or mislead future advocates.
(To be fair, the above is still not an argument about long-term impacts. But I think the related long-term argument that “good, lasting value change is more likely when it’s convenient” is a much better-grounded claim than “good, lasting value change is more likely when advocates have historical examples of entirely morality-driven change”; the latter claim seems entirely speculative, while the former is at least in line with various historical examples and psychological findings.)
Oh interesting, I wasn’t aware this point came up much. Taking your word for it, I agree then that (A) shouldn’t get more weight than (B) (except insofar as we have separate, non-speculative reasons to be more bullish about economic interventions).
Sorry for the confusion—I was trying to say that alt-pro advocates often have an argument that’s different (and better-grounded) than (A) and (B).
In other words, my current view is that (A) and (B) roughly “cancel out” due to being similarly speculative, while the separate view that “good, lasting value change is more likely when it’s convenient” is better-grounded than its opposite.
