Exploitation is when you place a worm on a hook to catch a fish. Its also using that fish to bait a bigger fish with.
exploitation (n.)
1803, "productive working" of something, a positive word among those who used it first, though regarded as a Gallicism, from French exploitation, noun of action from exploiter (see exploit (v.)). Bad sense developed 1830s-50s, in part from influence of French socialist writings (especially Saint Simon), also perhaps influenced by use of the word in U.S. anti-slavery writing; and exploitation was hurled in insult at activities it once had crowned as praise.
What are you? A slave? A worm? A fish?!
