I'm posting this here because one way to view the problems that our government (both under the prior admininstration, and, apparently, under the current one) is having with nationalizing the big, failed banks is precisely the inefficiency that David and Michele identify in their book: the entrenched elites, failures though they are in their own businesses, still have enough political clout and resources to lobby against direct federal take-overs of their failed institutions.
Johnson goes on to recommend increased antitrust scrutiny along the lines of Teddy Roosevelt's trust busting campaigns against the last century's robber barons. The interview is well worth watching.
