I know, it sucks. Here's the caveat:
WM (Costco, Sam's, Best Buy, yada yada) promise to provide X in sales tax revenue for town Y. Well, not exactly. These companies threaten to move to adjacent town Z if town Y doesn't ED the property that the company wants. So, the race is on between the cities and suburbs for who has the biggest tax breaks. Without regional jurisdiction/land-use planning, this kind of shiz will keep happening. Oh, and we'll be footing the bill.
