1. Bad policy clearly contributed to Detroit's situation, but bad policy alone is not responsible.
2. My point on Michigan's tax relief is that it is difficult to say that it is the reason for Michigan's performance. At this point in time, I do believe it made a contribution, though a modest one given firms' cost structures, but even that is subject to a degree of uncertainty.
3. In Michigan and elsewhere, an area in need of tax policy reform entails the transition from public assistance to work. One has to be careful that the effective marginal rates during that transition are not so high that they create a disincentive to make the shift.
