Food deserts are caused by crime, ranging from shoplifting to robbery, and a lack of reliable labor. If corporations, or even mom and pop shops thought that it was possible to make money, there would be no food deserts. The only color involved here is “green”.
In Britain, “food deserts” are white. South Asians (Indian, Pakistani, and variants), Caribbean Islanders, and Africans find their fruits and vegetables and they cook.
