Give a man a fish, and he eats for one day. Teach a man to fish, and, if he's lucky enough to learn this often tricky skill before he starves to death, which we've got to admit falls under the realm of possibility here - why the hell else would we even be talking about this? - then he'll be okay. If not, he starves to death.
So why not give him a fish, you selfish bastard, and teach him how to fish?
