See wars in history.<p>&gt;&gt;Inequality itself causes social problems.<p>Like what? Your USSR, North Koreas, Venezuelas of the world. In fact every failed communist nation in the past century falsifies this claim.<p>&gt;&gt;No single person can really be so much more productive than others as to justify billions in wealth; so if someone is that wealthy, they got that way on account of others&#x27; work, so they don&#x27;t deserve it. Economists are saying we need to reduce inequality to avoid disaster.<p>Appreciable sentiment if you till the land with a shovel in your hand.
