Chants of "equal pay" interrupted a speech by a top soccer official this week as the U.S. women’s national soccer team celebrated their fourth World Cup title. The players are suing over gender and pay discrimination. The players' fight for parity reflects the national battle for equal pay. A recent study shows women make 49 cents for every dollar a man does, over a 15 year period of their careers. I joined CBS This Morning to discuss ways we can start closing the gender wage gap.
