The author certainly does support that, it's not mutually exclusive to the next point. Is access to food, water, shelter, &c not a human right? In our current situation where literally every bit of land is someone's property, the class of people who have no property are absolutely dependent on a receiving a wage to survive. Employment will never reach 100%, so if you reject the policy of a universal wage, you are condemning the unemployed segment of the population to homelessness, starvation, and death. Also, many people do significant work, but are unpaid for it due to the way our society treats the social mode of production. A universal wage would partially resolve this.I thought the author was arguing for a greater tie of wages to value.
Instead he said, everyone deserves a basic living wage just because.
