I know of an area here that doesn’t have a single grocery store in four counties. They all had grocery stores at one time but they all slowly went out of business. All four counties are impoverished low and NO income areas. The lack of desire, education, and the lack of industry has destroyed the region. I would say 90% of the people live on government assistance. The people there didn’t patron the grocery stores and the theft level was high being in such an impoverished area. That is another reason convenience store owners justify higher prices. Crime is out of sight there. Convenience store owners can’t buy like large stores either so their cost is naturally higher. There was a movie some years back called “Falling Down” where they talked about such stores. When We had the Rodney King riots many of the store owners and their families were targeted.
