The UC was funded 100% between Wirtz and Reinsdorf... but they get massive property tax breaks from the City of Chicago.
Ideal model.
These CBAs should include venue allocations. I've been saying it all along. I think the tax payer and sponsor model alone has limited the capabilities of certain venues. Also, the fact that every team that plays there, including the away team, can benefit in the long run more than they do in the short run by building trash now. So if LA has the biggest Basketball market, and they could sell out 60k seats 90% of the time, the away team still makes 3x more, which aids them in building a larger venue, despite being a smaller market. It also takes the pressure off small markets from needing to keep up with the absolute biggest markets.
Tax breaks are good. But tax payers paying to build something is, as John Oliver points out, very destructive to municipal budgets. It's a major conflict. Some tax payers are fans of that team, some aren't. Some are fans of opposing teams, but you force everyone to chip in some how, some way.
The NBA and NHL have teams and sub-markets that could sell out a 40k+ seat arena. The NFL has teams and sub-markets that could sell out 150k+ seat arenas. Most cities with historical venues have enough demand to repurpose historical venues for many other purposes or even leagues. ie: Soldier Field could still play pre-season Bears games and host the Chicago Fire yet again. You could schedule a number of events that are off limits now, which essentially could aid to growing those events. It's silly in 2015 to have the 3rd largest city in the US with one of the most established teams in the league, playing in the smallest stadium.
