Professor Walter E. Block of Loyola University in New Orleans joined the show. We bumped into each other at FreedomFest. Prof. Block is nothing if not controversial. He's reviled by the left and has been the subject of numerous smears. He believes that homeless is caused, at least partly, by government policies of zoning, minimum wage and unionism. The solutions rest with the private sector as we see that government has been wholly ineffective in dealing with this phenomena. Prof. Block believes all that's required is that it be allowed to function. But we'll probably never find out, as government only gets bigger as a result of its failures.
