Levin is writing from a libertarian/individualist perspective and is blind to the existence of other world views.  Many economists also share this blindnerss.  He sees the egalitarian movements of the sixties and seventies-as well as the hierarchist/authoritarian movements on the right (such as the Moral Majority and the pro-life movement) as actions of individuals.  They are much more than that.  The civil rights movement still lives in the SCLC and Black Lives Matter.  Occupy is a quntessential egalitarian movement as is the gay rights movement.  He is blind to the nature of collective action, however, so he misses a lot.
