I'm hoping someone can help me find an author with some really vague clues.

First let me say that I'm terrible about remembering authors' names and can sometimes barely remember titles. I had heard this author speaking on TV and he was talking about ways that savings and loans have more money than all the major banks put together. He also talked about using urban environments to raise food and how plowing money back into the infrastructure would aid the economy and at the same raise employment. Yeah I know he sounds like a lot of people but his arguments were accompanied with well thought out plans. I was so enthralled with his message I wrote his name down so I wouldn't forget it and then lost the paper.

The only clue I have now is that I saw him on TV. I ran a search on Stewart and Colbert for their guests and came up with nothing. I then checked out the authors on the Book Notes program and again nothing. I think he might have been a professor. So now my erudite and computer savvy DUERS any ideas?
