...to create the jobs that are created makes a lick of sense. On the other hand, I've seen more than a few that show negative impact, no impact or very little impact for the money spent, in terms of benefit to the local economy. In fact, I've yet to see a study that shows much in the way of actual job growth. Further, most studies I've seen indicate that the jobs created are lost elsewhere, as entertainment dollars are moved. If you think that those cities couldn't have revitalized their downtowns for less money without those stadiums, that's your choice. It's been done in Portland, Oregon, for example, where a once ignored downtown is far livelier than Cleveland's, stadium or not. In the end, restaurants and businesses in other parts of town get hurt, because they're not subsidized, while the already wealthy make even more.
I think you are overstating the supposed benefits by a great deal. The cost does not match the benefit, if there is a true benefit.
