All built, of course, with taxpayers' money. In English, this means taxpayers help pay for a building owned by billionaires, who, in turn, pay millionaire athletes. Here's the problem. The studies don't mean jack. But economists dispute the multiplier effect.
Local economies are very leaky.
Money that you spend on a ticket or on a concession or something like that doesn't just circulate throughout the city. Often it gets out of the city almost instantly. So the same entertainment dollar merely went here instead of there. Sorta like rearranging the living room furniture, without actually buying a new sofa. However, economists estimate that 90 to 95 percent of sports patrons come from the local community.
