Wow that's a bit offensive to those that live in Minnesota...there are plenty of wealthy people that live in Minnesota, ever heard of the Mayo Clinic, 3M, Best Buy, General Mills or Northwest Airlines? Not to mention we have one of the largest malls on the country, and we like sparkly things too.
If you're offended, then I think you're missing the point.
IMO- The point is- many businesses overexpanded in boom times and now cannot support the debt taken on during the expansion. It really has nothing to do with whether or not there are people in the new areas who can afford to shop. Of course there are, that's why it seemed like a good idea.
In the case of a business like Tiffanys, they also may have made there brand less exclusive and coveted by making it so accessible. A part of their success was built on being exclusive. I know that on our trips to NYC a stop at Tiffany's is no longer as big a deal since we can visit the store in San Antonio.
