The Supreme Court’s recent decision in the case of Walmart v. Duke has reignited the national debate about unequal pay that many women face in the American workplace.

Today in America, women are paid on average of 80 cents for every dollar paid to men. For African-American women, it’s 70 cents on the dollar. For Latina women, it’s 60 cents on the dollar.

This means that each time the average woman starts a new job, she starts from a lower base salary. Over time, that pay gap becomes wider and wider. From the start of her career to the end, the average woman stands to lose $380,000 over her lifetime. That means $150 less in her weekly paycheck. It means nearly $8,000 less at the end of the year. When women start at a disadvantage, they stay at a disadvantage. And we all lose.
