Years ago, commissaries and exchanges provided the only low cost shopping options that were available to military families stationed in isolated locations. Today almost every military base has a Walmart Supercenter and several other grocery stores right outside its gates -- all crowded with military shoppers. Those stores have found their way to military markets for two reasons:
1. Almost all military members now have their own cars to reach them; and
2. Military families have the money to buy from them.
Aboard any large base today you'll find McDonald's, Burger King, Subway and Pizza Hut franchises; similarly, the need no longer exists to justify parallel supermarkets operated and staffed by highly-paid government employees. On-base shopping can be outsourced to any number of regional supermarket chains -- or in total to Walmart, whose nationwide logistical system would require only minor tweaking to meet the demand.
Subsidized military commissaries and exchanges needlessly and inefficiently duplicate what the private sector now already provides. They are no longer needed and no longer contribute to national defense, and therefore should be closed.
Why don't we cut EBT and all the rest of the welfare programs for social parasites that do nothing to contribute to society and use that money?
Then if there's still problems, get back to me on closing the commissaries.
