Local tax/economy

So the big deal here in Austin is the local city officials are giving the worlds most profitable company, Apple, a tax break for what amounts to be no good reason. Tonight this headline showed up in my inbox ""Triathlon events to bring 600 athletes, $700K to Butler Co." why are local councils so gullible?

In this case it's a youth and Junior championship organized by USAT. You read here. I struggle to see all in that the local municipality could get in that sort of money. Sure since its a championship a lot of people will stay at hotels, eat at restaurants etc. Thats over $1100 per athlete... even with entry fees, hotel for a couple of nights and a few meals thats a stretch. Figure in the price of gas and driving...
