Absolutely fascinating topic and, unfortunately, a quite uncommon research theme. I bought this book as soon as I heard of it. I would add that this research shows class within the UK but one could make the case for international elites also being brought up to have advantages regardless of where they go. I’m talking about social capital, levels of education (at the right, well-known institutions), and professional connections.
Reddit brought me here after Dr. Friedman's book was cited in a recent virally upvoted post, "The plateauing of cognitive ability among top earners." This is wonderfully important work. Does anyone know of studies like this, but focused in the United States?
