The graph above is from the new book Black Stats: African Americans by the Numbers in the Twenty-First Century, by Monique Morris. Essential reading for those interested in the issue of inequality in the United States. Not only blacks and latinos make considerably less, the gender gap matter too. Interestingly enough, the gender gap might be smaller among minorities. From the book:

“The gender wage gap among African Americans is smaller than that for Whites, largely because African American men earn much lower wages compared with men in other racial groups. Black men employed full-time earn on average $653 per week, 76 percent of the average salary earned by White men, and Black women earn on average $595 per week, about 85 percent of the average salary earned by White women.”

Some of these issues are explored in more detail in this paper by Huato and Zeno (2009).
