b_b and cliffelam, Jack makes a good case for not building the stadium. Cliff, have a listen to this if you can. Lessenberry has an old school media voice that you either like or hate. I tend to like it and his writing. He makes some good points.
Except that it's not the city paying. It may not benefit the city in the end; time will tell. But either way, no money is coming from the city's tax collections. The money is coming from a mix of private capital and state issued bonds, which are basically safe. Detroit's finances and Michigan's finances are quite different.
