It seems like professional sports franchises are always trying to get the cities where they’re located to pay for new stadiums. The most common tactic is to simply blackmail the citizens of the city by threatening to move elsewhere, but along with that there’s usually some study or another talking about how much better off the city will be financially with the new stadium. Well, as it turns out, those studies are a bunch of crap. Professional sports doesn’t a thing financially for the regular joes who eat the cost of new stadiums.
