There are two trains of thought on the subjects of public financing of sports stadiums, Howard. One being that the added activity, such as parking fees, restaurants, souvenirs, hotel rooms, etc., will generate tax income the city would not otherwise see. In fact, owners of the teams hold it as a club over the heads of the cities threatening to move their team to a friendlier city if a new stadium isn't built.
However, the other thought, backed up by a lot of data, is that years after being built, the stadiums still aren't paid for and the city has actually lost money that could have been used for more useful projects... escpecially in blighted areas.
It comes down to any major city wanting (along with the fans, of course) sports teams for the ego stoking that goes along with it.
Actually, (on another metioned subject) we read here that NHS is not doing that well and health care in the U.K., for all practical purposes, is rationed and will become more so in the future. Canada is deep in talks to restructure their own government funded (read: taxes) system.
About every other week or so, we see news reports aobut Canadians that can't get needed services and elect to come to the U.S. and pay for it, getting it quickly and efficiently.
Thing is, world-wide, health care is going to continue to eat up major sections of governemnt funding and severe rationing will be the result. A government can offer full and unlimited healthcare because people, being people, will jaunt off the Doctor's office each time they have a twinge... in y opinion...
