Specifically, "Claims that the NFL is using a tax exemption to avoid paying the tax due on these revenues are simply misinformed. The confusion arises from the fact that there is one small part of the NFL, unrelated to all this business activity, that is tax-exempt: the NFL League Office. The league office is the administrative and organizational arm of the NFL and does things like write the rules of the game, hire referees, run the college draft, negotiate the collective bargaining agreement with the players, conduct player safety research, and run youth football programs."
The fact that NFL teams get taxpayers to foot the bill for new stadium construction and then the team retains the facility as private property, now that is what I have a problem with. Those facilities are bought with public money and should be public parks.
I generally agree with the principal you present but you have to acknowledge that the government (and therefore, theoretically, tax payers) gain value through the stadiums presence in the community. More directly through sales tax and tourism but possibly other less direct means like property values and property taxes.
Furthermore, if that's what people want to be done with their tax money, that's their business. If enough people felt the way you do, the story would be different. See the San Diego Chargers situation for example. They may end up relocating because of lack of political backing on building a new stadium.
We only establish or change what "people" want done with their tax money by public discourse on whether we think it's a good idea. That something is done by the government is hardly a reason to not question it.
