Not when they can get tax payers to foot the bill, and then move the team to a new city and a free new arena. I realize that "the colosseum" is more symbolic, but I wonder what piece of infrastructure capitalists ever provided for themselves. The railroads, canals, and FREEways as National Security were all great gifts to Capitalists. To get a factory to relocate, the state and local governments give away the store (tax relief as well as actual construction). And don't get me started on DARPA provision the monopolization of the Internet. Capitalism is actually all about privatizing the commonwealth.
