Planck’s Constant runs with the Larry Elder “rioting” column:
San Francisco’s Chinatown in the 1960s was one of the most impoverished areas in California, yet tourists were not afraid to patronize Chinese restaurants or to walk about without fear of being accosted, raped, mugged, or killed.
Because of their culture and values, the Chinese throughout America thrive. On the other hand, no sane person would knowingly enter a ghetto area to grab a bite to eat or to buy something. And so you do not see black retailers in ghettos except for barbershops.
