Essays / Political Science Essay Question - formulating a thesis [6]

Thanks for the response.. I should have clarified it more. I was thinking of focusing on the government role in the situtation as a main goal of Bill Clinton was to create affordable housing for the lower class. So I would chronicle how it went from that goal and led to future policies that were passed that were influenced by Wall Street's lobby in Washington. I just need a good focus and clear hypothesis so I can begin the paper. It would be easy if it was just about pure policy but my professor wants it about "public policy theory." Any tips would be greatly appreciated.

If you or any of your colleagues have any insight about public policy theory that would help too. I've never really come into contact with it before.
