Are churches ever BAD for a town?

I would not have thought it was possible to have "too many" churches in one town, but it appears there is at least one case where it is possible. Stafford, TX has 51 churches in 7 square miles. "So what?" You ask. Well, apparently no one else is moving in, leaving a town with far more tax-exempt institutions than taxable ones. And the churches are primarily catering to out-of-town Christians who come into church, and leave no taxable income behind outside of the church. The town is now looking for ways to keep churches out.
