Parable of the Rich Man.

A rich man was once content to live in his garden. Then poor people moved nearby to drink at his spring and pitch tents against the wall of his compound. When he was among these people, instead of helping them drink, or live in the shade of his wall, the rich man was no longer content with what he had. Now he wanted more. Everything he saw he wanted it, or ten of it. Not that he could use another spring or another wall, but he wanted all the springs, and more walls. He built more walls to keep people away from his walls, and capped the springs he could not use, buying all that he could buy.

Soon, all the buildings and springs in the area belonged to the rich man. Then the poor people moved away, and left to him everything the rich man owned. Now he wanted only to live in his garden. He had no use for the buildings and springs. He could only drink what he could drink, and could not enjoy even one compound when there was no one around who could see that he was the one who owned everything.
