"Since effective altruism is committed to whatever would maximise the social good, it might for example turn out to support anti-capitalist revolution." (Srinivasan 2015)
In this peer-reviewed article for Moral Philosophy and Politics, I explore this suggestion. This connects with my EA forum piece 'Why not socialism?' but is more thorough and more focused on longtermism in particular.
ABSTRACT: Capitalism is defined as the economic structure in which decisions over production are largely made by or on behalf of individuals in virtue of their private property ownership, subject to the incentives and constraints of market competition. In this paper, I will argue that considerations of long-term welfare, such as those developed by Greaves and MacAskill (2021), support anticapitalism in a weak sense (reducing the extent to which the economy is capitalistic) and perhaps support anticapitalism in a stronger sense (establishing an alternative economic structure in which capitalism is not predominant). I hope to encourage longtermists to give anticapitalism serious consideration, and to encourage anticapitalists to pursue criticisms of capitalism’s efficiency as well as its injustices.
(my apologies for commenting here without having read your academic paper)
I suspect that two major elements prevent anti-capitalist ideas from being more popular within EA.
And that isn't even getting into the tractability element.
If the leader of some organization (say, the Catholic church) were to make a statement that capitalism is bad for people and a different economic system should pursued, many Catholics would (to varying degrees) disagree, disrespect, or leave the catholic church. Even people who are not part of the catholic church would talk about how ridiculous the church's statement is. It would make it harder to convert people to Catholicism.
I have vague conceptions of worker's communes from documentaries I've watched, and I've read plenty about ways that non-capitalistic systems have failed, but I have a paucity of examples for ways that non-capitalistic systems have succeeded. I'd love to live in an intentional community with respect and equality and each contributing according to their ability, but I have no idea how that would work on a society-wide scale. So although the idea appeals to me, it is hard for me to envision how it would actually function.
