Exactly. Bigger government is not always worse. Most stadiums have a mix of private/public money in the project because it benefits you and me (taxpayers) to have a steady stream of income coming in for years to come.
In 1993 San Antonio passed an increase in sales tax to pay for the Alamodome. $186 Million. When funding was complete, the tax was revoked. Did we ever get an NFL team? Nope. But it satisfied the Spurs enough to stay in San Antonio. and it has more than paid for itself in just Alamo Bowl benefits. 40 to 50 million dollars spent here in SA each time the Alamo Bowl is played.

And that's great if that is what the local community wants. But I will note that San Antonio taxed for and built a new football facility that did not previously exist. The Bradley Center already exists. There is no "need" for a new arena. The other major tenants of the Bradley Center - Marquette University & the Milwaukee Admirals hockey - franchise are entirely happy with the facility.
If government leaders and their constituent taxpayers Milwaukee County or the City of Milwaukee want to subsidize a new arena for NBA millionaires and billionaires, great. Go for it.
But I didn't help elect a Republican state Assembly, state Senate and governor so that State of Wisconsin tax money is used to benefit liberal Democrat NBA players, NY-based liberal Democrat owners and liberal Democrat Milwaukee politicians.
