Stiglitz on Inequality

Available for over a year

Joseph Stiglitz explains why he thinks the gap between rich and poor has grown so wide. The Nobel-prize-winning economist tells the BBC's Ed Butler why, in his view, precious little is being done about it. Also, we hear from Marie Keyworth in Haifa in northern Israel on how the local heavy industry - which is set to be expanded - is accused of causing air pollution and cancer among the residents of this coastal town.
