professor hartman, thank you for being with us. i want to ask you a basic but specific question. do american women make less than men while doing the same work? >> it's tricky, doing the same work. there are many companies where they would get the same pay. but many companies where they don't. and the 20 largest occupations for women, ones that sound the same. customer service representative, making 94% of what men make in customer service work.
