The American Dream is a myth, says Nobel-prize winner

It has become increasingly difficult for Americans to climb the economic ladder, says Joseph Stiglitz, a Nobel-prize winning economist.

The U.S. has one of the highest levels of income inequality among its peers and is among the worst in offering equal opportunities for advancement, said Stiglitz, who spoke Tuesday in New York City. Whether an American gets ahead is also more dependent on the income and education of their parents, he said.
