Produce isn't the main profit driver maker for grocery stores. The presence of dollar stores can keep actual grocery stores from moving in, leaving communities with no access to fresh foods.
Should I feel bad that my healthy produce is subsized by suckers who buy boxed junk from the shelves?
I caught this on NPR Now last weekend. It's the same story with more depth, mostly following the saga of north Tulsa not being able to attract a proper grocer because it has become saturated with dollar stores.
