The greater the economic divide, the greater the appeal of revolutionary change. When the rich keep getting richer, while schools are crumbling in need of repair, while drinking water is poisoned, while life-sustaining medicine is not affordable, while jobs pay less than a living wage - so long as the damage and inequality is deep and tragic, socialism attracts. Those who make peaceful revolution impossible make violent revolution inevitable. If you wish to avoid a full-up socialist revolution, tweak your capitalism to end the evil it produces. Capitalism fails when the leaders take the "let them eat cake" attitude, failing to act for the greater good only to line their own pockets. Now what were you saying about pre-existing conditions?
