What's the price of a Super Bowl?

Let me begin by stating that I’m a sports fan (not a rabid fan) but a fan nonetheless.  I prefer college sports because somehow I hold onto the notion that it’s still somewhat pure competition even though I know it too is all about big money.  And that’s why I’m thinking about the cost of a Super Bowl…

Typically, urban areas like Minneapolis use tax payer money to build stadiums with the acknowledgement a professional organization like the NFL will reward the city with a Super Bowl.  In the last seven years 12 cities have built new stadiums and by 2020 all 12 will have hosted a Super Bowl.  The state of Minnesota spent $348 million accompanied by $150 million from the city of Minneapolis accounting for nearly 50% of the new U.S. Bank Stadium.  Reasonable studies indicate that cities/states get a return rate anywhere from $30 to $130 million in economic activity associated with hosting a Super Bowl.  

Hurray for new England and Philadelphia!  Sports provide a powerful bond across America. I just cannot help but think of how this might help a state economically if it would make even a one-time investment of $348 million into the Super Bowl of life known as the public education system.
