Equality for women in the U.S. is still an uphill battle, the wage and leadership gap a challenge 100 years after passage of the 19th Amendment.

Joe Grundfest, a former SEC commissioner and expert on corporate governance, and Gail Harris, who serves as lead director of investment banking advisory firm Evercore Inc., discuss the law, possible challenges to it, and why it matters in this episode of Stanford Legal.
