Should taxpayer funds supplement professional sports stadium projects?

I'm having trouble getting on board with the Twins stadium, and, now, a Vikings stadium  asking for tax funds, when our state's infrastructure is failing (see 35W bridge collapse/rebuild updates).

Should government be in the sports business? How much do they truly get back in revenue and jobs?

I'd rather see my tax dollars go to something a more practical. If I want to support sports, I buy a ticket with the money I have left after taxes. And, I'm not a sports hater - I do buy tickets - I love sports and nice sports venues. I also like safe roads and great schools.

When we can't have it all, I'm willing to give up the fluff.

This article on MinnPost addresses the issue:

"But, still, it will be about the deal, about which public entity will get involved — yes, there will be a call for public financing — and then, of course, how much owner Zygi Wilf and his partners will invest.

The Twins' ballpark financing model of partnering with Hennepin County won't work. Another local sales tax increase would create riots along Nicollet Mall. The concept of  "a local partner," as Gov. Tim Pawlenty likes to call it, is off-base. If any government account benefits from pro sports, it is the state's (via income and sales taxes) and it is the state — of any government entity — that will have to come to the table on this massive project."

Does the state really need to come to the table? Isn't it the Vikings and Twins that need to gather investors and pony up the cash?

Does anyone else have thoughts to share? I'm open to different perspectives.

Maybe someone with another point of view can address the benefits of these investments and explain why it's a good use of tax funds?
