The Occupy or "99 Percent" movement has as many main points as cities. Ralph Young, Temple history professor and author of Dissent in America, was involved in 1960s protests. He sees unity in diversity. "In all protest movements," Young says, "everybody's got their own reasons for being there. But economic injustice — that involves thousands. This person's issue will be a lost mortgage; this one's is no jobs. These protesters want the government to listen. 'We are screaming in pain and all the government listens to is Wall Street,' they're saying. Under that umbrella come many other things."
