While global wage equilibrium would be great, how do you deal with the challenges that large, diverse societies already have in governing effectively? It’s tricky to build a “good feeling” cultural/legal/political landscape for 300MM people of diverse languages, religions, education levels, etc. I think we can eventually get there (we are getting there... via globalization), but it must be gradual. Thoughts on this problem? (Sidenote that wage equilibrium != outright wage equality)
