Grocery stores usually LIKE to locate where there is a lot of people and a shortage of competition
Maybe there is some other reason they don’t want to locate in those neighborhoods?
(hint- it’s not racism, everyone’s money is the same color)
How about because they don’t like getting shoplifted out of business?
I had a family member who owned a store- although it was in an upscale mall that was 90% white customers, 90% of the shoplifters were minority. She had to stop taking checks from everyone so as to not have to ‘discriminate’ against certain groups. She had to plaster the place with mirrors and video cams, to discourage theft- rather than catch them and spend all her time in court trying to prosecute, which usually failed.
It is racism: some people don’t like Koreans or other Orientals.
