Veterans of past social movements, such as Young, say the Occupy Wall Street protest has been a welcome response to the abysmal economy and has the potential to galvanize wide support, but whether it will lead to lasting political change remains to be seen. “There’s a difference between an emotional outcry and a movement,” said Young, who worked alongside the Rev. Martin Luther King Jr. as a strategist during the civil rights movement. “This is an emotional outcry. The difference is organization and articulation.” (AP Photo/Jacquelyn Martin, File)
