The 2012 SB in Indianapolis cost the city about $8m in extra expenses.
Of course if you believe the politicians, that was trivial compared to the “economic benefit”.
And I must say compared to the $750m we are shelling out for the new stadium, it’s hardly noticeable.
Spending tax money on stadiums has no economic benefit to people other than the billionaire owners of the team.
Maybe Indy did have a benefit from the Super Bowl, but for places like Miami it really doesn’t because all it really does is displace tourists who would otherwise be there.
