It kinda does, the "lower class" here is violent and mentally unstable, the "white-collar club" is non-violent and functional in the prison environment, in spite of their best attempts to try and to throw in a racial aspect no evidence is brought that it plays a role, no hints or accusations that money is used to bribe guards or prison authorities. Anyone with basic penology background will consider it a textbook success on progressive grounds - the default in most places is that the prison "upper class" are the violent career criminals who keep the population in check for the prison guards as the white-collar prisoners pay them protection money.
