I&#x27;m not sure that any system doesn&#x27;t need &#x2F;any&#x2F; altruism. It may be the case that systems which do not require much altruism to function work better, because there is a higher chance of the requirement being met, but I think that a good system would also have mechanism by which altruism can provide further benefits.<p>If what is required for people to act in a way that benefits others is for the people to be motivated to act that way, it seems that people being motivated by the benefit that their actions have for others would be a good motivation for them to act that way, as far as it is an available motivation.<p>Which, seems compatible with some senses of the word &quot;capitalism&quot;. People value their own well-being, and the well-being of others, by some amounts, and based on that, take actions and make agreements with others so as to serve these ends as they see fit.<p>Of course, in that sense any system could be seen as a sort of capitalism, leading capitalism to be almost like a tautology?<p>Which doesn&#x27;t seem to match how people use it, so either I don&#x27;t understand the intent behind how people use it, or, uh, it&#x27;s almost kind of empty? Probably the former.
