"Human life is not some sort of race or game in which each person should start from an identical mark. It is an attempt by each man to be as happy as possible. And each person could not begin from the same point, for the world has not just come into being; it is diverse and infinitely varied in its parts. The mere fact that one individual is necessarily born in a different place from someone else immediately insures that his inherited opportunity cannot be the same as his neighbor's."
