A quote from Sowell's latest:
...I received a letter recently from a man who grew up in my old neighborhood back in Harlem. When he and I were in the same junior high school, one day a teacher who saw him eating his brown bag lunch suddenly arranged for him to get a lunch from the school cafeteria without having to pay for it.
It happened so fast that my schoolmate had already taken a bite from the school lunch when he suddenly realized that he had been given charity-- and he wouldn't swallow the food. Instead he went to the toilet and spat it out.
By now his brown bag lunch had been thrown out, so he just went hungry that day. He went on to become a very successful psychiatrist.
