Meanwhile, in the black part of Tulsa, Social Pimps, er, Activists, bemoan the fact they have zero, count ‘em, zero quality grocery stores. But what they fail to address is that no reputable company is going to open a large grocery store in an area of town where shrinkage is guaranteed to exceed profits.
And a national chain CANNOT charge higher prices in minority areas. So it's either operate at a loss, or don't go there at all.
The only places which can operate there are independents (with no deep pockets to attract lawyers should the owner have to deal with shoplifters/robbers). Independents are free to charge higher prices (to compensate for higher costs/risks) and impose security measures that would be negative PR for large chains.
