I expect you to tell me where in that PDF is anything supporting your original statement that "Many of these workers are from the prison industrial complex. Pay is non-existent or abysmally low, AFAIK.". That PDF puts Amazon on one huge list of companies, without saying in what exact manner it has anything to do with "prison-industrial complex" at all. Can you quote anything in that PDF that says anything specific about any connection of Amazon with prison-industrial complex?
