“I am wronging no one,” you say, “I am merely holding on to what is mine.” What is yours! Who gave it to you so that you could bring it into life with you? Why, you are like a man who pinches a seat at the theater at the expense of latecomers, claiming ownership of what was for common use. That’s what the rich are like; having seized what belongs to all they claim it as their own on the basis of having got there first. Whereas if everyone took for himself enough to meet his immediate needs and released the rest for those in need of it, there would be no rich and no poor.
