What does Grigg mean by "learn to live in the South?"

he means that the way Wright is living now, he is doomed to die or get killed. he loses job after job because he does not degrade himself to be lower than whites - both inwardly and outwardly. and now he is looking for a job, and griggs tells him he wont be able to get a job, let alone keep one, let alone have enough money for food to survive, unless he sells out to the white system - the system of the south. Griggs means that Wright needs to act BLACK. he needs to act like he knows he is less than all whites, that he needs to get out of their way. he doesn't have to believe it - but he needs to live in a way where he is inferior, where he doesn't question white people - and he treats them like every other black person treats them. if he doesnt keep his mouth shut, he will get killed, no question.
