author Kameshwari Pothukuchi wrote that many supermarkets left mixed-income central city neighborhoods after civil disturbances in the late 1960s and 1970s, following customers who left those areas during “white flight” — and they never really returned. “Supermarkets have abandoned the inner city for suburban and exurban locations,” Pothukuchi wrote. “Which offered more land for parking, easier loading and unloading by trucks, convenient access to highways and arterials, and a development context for much larger stores.”
