Research suggests women the bigger bread winner over men

New research suggests women are earning more money than men.

According to Liza Mundy’s book The Richer Sex, single women in their 20's with no children on average, make more money than men. 

Almost 40 percent of working wives out-earn their husbands and that number is rising.

Mundy said over the next few decades, professions like law, medicine and veterinary medicine will be predominantly run by women.
