See, here I thought it meant "he who smiles at a thief does so because he's actually made a bigger theft from him." Like a car buyer thinking he just got a sweet deal on a mint-condition classic by taking advantage of the dealer not knowing its real worth, while the dealer is just smiling because he knows under the hood is a transmission full of sawdust.
"If ye love wealth greater than liberty, the tranquility of servitude greater than the animating contest for freedom, go home from us in peace. We seek not your counsel, nor your arms. Crouch down and lick the hand that feeds you; May your chains set lightly upon you, and may posterity forget that ye were our countrymen." -- Samuel Adams
