The jock tax is the least of the reasons to do that. There will be entertainment replacements. Concerts (pop, symphony, or just the local bar), vacations to the Dells, additional trips to theaters (of which there are a lot in Milwaukee), museum visits, comedy shows, etc. Players' salaries are paid by entertainment revenue from fans, and a lot of that revenue will simply shift to other forms in Wisconsin. Yeah, I don't expect that there will be 41 concerts at the Bradley Center just as big as the Bucks, but I don't think entertainment expenditures in SE Wisconsin are going to decline by 100% either, most of it will shift forms and be spread around. I'm more open to the argument that a new arena will be a catalyst for new investment in downtown Milwaukee. But, I also worry that excessive tifs and other subsidies are going to starve the city of needed revenues for things like police and fire services. Does a slew of new restaurants near a new arena hurt the Third Ward? Are you creating new demand or are you just shifting demand from one area to another? In short, I'm skeptical of a sports entertainment district being an economic panacea. Especially since nobody can really point to a large population migration as a result. Especially with the State budget as it is and education and roads being shortchanged in the current budget. If given the choice between infrastructure, education, and sports entertainment, I tend to think you get more bang for your buck from the first two rather than the third. If given the choice between the UW system and the Bucks, I'll take the former.
