Groucho Marx explains to his unpaid workers how capitalism works, in The Cocaonuts (1929):
"Wages? You wanna be wage slaves, answer me that? No, of course not! But what makes wage slaves? WAGES! I want you to be FREE! Remember there's nothing like Liberty! (Except Collier's and the Saturday Evening Post.) Be free, my friends! One for all, and all for me! And me for you, and three for five, and six for a quarter!"
