"One percent of the nation owns a third of the wealth. The rest of the wealth is distributed in such a way as to turn those in the 99 percent against one another...Against the reality of that desperate, bitter battle for resources made scarce by elite control, I am taking the liberty of uniting those 99 percent as 'the people.'"
Not only is it clear from the text that this is the origin of the Occupy movement's "99%" mantra, but the Occupy movement is advertising on the very webpage of the book which discusses this issue. No wonder: over 1 million copies of this textbook have been sold and used at high schools and universities across the country in the past 20 years.
