In nearly every major city, housing the homeless is a major problem. Since the defunding of residential mental health programs in Reagan era, the dramatic cost of housing, and other cutbacks in the welfare safety net, America created a huge population of people with problems who have nowhere to live except outside. Especially in California, which has the most homeless citizens in America, everyone recognizes the problem but there's complete lack of political will or consensus to significantly address it. Even with the better ideas, there's a generally well-funded, lawyered-up constituency that's going to fight it. Joining us today are the authors of the new book Housing the Nation, architect Alexander Gorlin and architectural historian Victoria Newhouse, with their take on what to do.
