Tax dollars for Stadiums. I think not.
There are many other uses for such important resources and the resources should not be squandered.
Sports Stadiums are becoming very expensive items to build and maintain. Unfortunately too many teams use the lack of a "modern" facility as leverage to extract tax dollars to build stadiums using the threat of moving to another location if the request is not granted.
What is a perfectly serviceable venue to watch a sporting event may not have been designed to take into account some of the more profitable seating arrangements like sky boxes for the rich and famous.
The neighborhood may not be convenient for parking or the neighborhood may be perceived to be undesirable for the swells that were once the peoples who filled the seats.
Owners of professional sporting teams are aware of the potential goodwill a sports team can bring to an area and are able to use that situation to access tax dollars, subsidies and other concessions that put the public on the hook for massive expenditures through studies that are sometimes actually wrong but more often overstate the benefits in dollars and cents and do not make proper comparisons about how the monies might actually be spent.
Too often the source of the funds for a sports venue or an arts venue comes from a bed tax or a tax on rental vehicles.
Look at a hotel bill from a resort city, it is not small change and can add 10% to the cost of staying in Miami or Orlando. Maybe a hotel owner or restaurant would benefit more from a longer stay. College Bowl games and the occasional Super Bowl is touted as a major event that provides publicity that money can't buy. It's being bought for sure but the costs are often not explained properly.
The venues themselves are not used many days and the people who use them are just as likely to be local residents as tourists. The most likely problem is that there is a limited amount of money for entertainment to be used by each family and once used it's gone from the budget.
Short term public works projects do provide construction jobs and those jobs usually pay good wages if local people are hired for those jobs. Too often many of these construction jobs are being filled by people from outside of the community and so the local benefit is minimized. Jobs after the venue is built may be low wage jobs in the service industry selling hot dogs or souvenirs.
The main beneficiaries of the public works projects are owners who are franchise owners of a monopoly that can be sold for hundreds of millions of dollars and the players for these teams. Except for the Green Bay Packers I am unaware of a major professional team that is owned by the locality they serve. Unfortunately many of the players on these teams have no loyalty to the place where they play and often build houses in places far from the team.
If it makes you happy or proud to have a major league team so be it. Unfortunately you don't own even a small part of the team and may not be able to attend a game in a building you helped pay for through taxes you have very little control over.
