Teresa Schmid has written The Lawyer-Rent Seeker Myth and Public Policy. Here is the abstract:
Two enduring fallacies in public policy are that lawyers are rent seekers who impair rather than stimulate the economy, and that there are too many of them. While lawyers may disagree with the first premise, they tacitly accept the second. These two fallacies have led leaders in both the political and professional arenas to adopt policies that impair access to justice. This study documents the negative effects of those policies and recommends courses of action to reverse those effects.
