I hope the teacher who said #11 isn't teaching reproductive biology.
The sperm that makes it through to the egg doesn't get there first. Multitudes of other sperms die weakening the wall, receiving nothing in return, only for another to slide right in and reap all the rewards and renown for their sacrifice. It's basically the perfect analogy for capitalism.
The free market is not, as the social Darwinists imagine, a struggle between rich and poor, strong and weak. It is the principal means by which human beings cooperate in order to live. If each of us had to produce all his food and shelter by himself, almost no one could survive. The existence of large-scale society depends absolutely on social cooperation through the division of labor.
