There's circumstantial evidence that it's hard to get hard direct correlations between these campaign contributions and the policies we observe. Liability and tort reform presumably have been hampered or killed by that effect. And they certainly, lawyers as a group make large contributions to politicians. So let's go back to the book. As you say, you spend, the book by the way is quite short. It's about 110 pages, I think. It's under 120. Short. A chunk of it is tries to estimate empirically the premia that lawyers earn due to these effects of restricting supply and increasing demand.
