Jason Brennan, an associate professor of philosophy at Georgetown University says in his new book that thinking that Socialism is the best way to run a society neglects the fact that even in utopia people will have significantly different visions of a life well lived.

You want a system under which you can realize all these different conceptions of the good life and the good community, Brennan argues. Even in a world free of petty rivalries, tribalism, and human failings, capitalism would still be superior because it uniquely affords citizens the rights and freedoms necessary to customize their lives and pursue their own, personally meaningful projects.
