How many reports to spark a serious policy discussion?

So it was asked by a friend of mine in response to the report just released that Michigan's economic development tax breaks may not be working.  No surprise to this writer as other reports have concluded that various economic development and transportation incentives have a) resulted in sprawl, and b) not created long term job growth as is always promised.   The first conclusion comes from a 2006 report by Greg LeRoy of "Good Jobs First", the second from a 2007 report by Professors Gary Sands of Wayne State and Laura Reese of Michigan State.  Its time for the state legislature to thoroughly review the kinds of incentives we have on the books and move to those that reflect how jobs are created today -- by one's and two's -- and ensure that such resources are targeted at those communities with existing infrastructure; a key recommendation of the Governor's Land Use Leadership Council report from 2003.
