Why do Taxpayers have to foot the bill for sports stadiums?

Maybe people put some value in the prestige of having their city represented in a major league. Youvare right it is not a big economic boost. I hate it when the billionaire owners threaten to move the team unless they get more subsidies for a building replacement

Because politicians make bank from these transactions

Because sport enables us to be free. A cursory glance at the adverts will confirm this.

because testosterone is at the helm.

I agree completely.
