>Bases also open and operate large sales tax free stores for service member and family use (base exchanges).

Those aren't accessible to all the civilian workers and contractors who work on-base.

>Military housing, as long as owned directly by the federal government, doesn't pay property taxes

Civilian workers and contractors are not military, and don't use this housing. They live off-base, and pay property taxes and sales taxes. With the generous paychecks they get (relative to the locals who work at Walmart), they can afford to buy or build much larger houses and nicer cars, so they pay a LOT more in property taxes.

>I'm not saying military bases don't add to the local economy, they do, just not anything like a civilian operation of a similar size.

No, what you're really saying is that you have no clue at all what goes on on a military base, and you have some ignorant idea that everyone there is in the military when in fact it's usually a small minority of people on-base who are active-duty military.
