Today, April 9, 2013, is the 50th Anniversary of the Equal Pay Act of 1963, which prohibits sex-based wage discrimination between men and women in the same establishment who perform jobs that require substantially equal skill, effort and responsibility under similar working conditions. Although much has changed since those days, wage disparities still exist - in some surprising areas. From Politifact.com:

For computer programmers, for instance, women earn 95 cents for every dollar a man earns. For cashiers it’s 92 cents. For cooks and customer service representatives, it’s 95 cents. Other occupations have more unequal ratios. Women who are personal financial advisers, for instance, earn just 58 cents of what men in that job earn. (The statistics come from the Institute for Women’s Policy Research, a think tank focusing on women’s issues.)

To commemorate Equal Pay Day, today, April 9th,  a group of Louisiana women legislators are wearing red to signify Louisiana women are still 'in the red' when it comes to wages.
