This is not the history of labor unions, tho they are certainly included. It’s broader than that, the history of how Americans have made a living over the centuries. The main (but not the only) text is Henry George’s Social Problems, a very accessible work, which does not presuppose any particular understanding of political economy. More about the course is here. Meets for ten weeks, every Tuesday thru November 19. Preregistration is available here, or just show up and sign up after the first class. $25 fee covers the entire course.
