Our happy hour fact to amaze your drinking buddies with.

Single, childless women under the age of 30 earn significantly more money than men of the same age.

James Chung, of Reach Advisors, studied the Census Bureau's American Community Survey and concluded that in 147 out of the 150 biggest cities in the United States, childless, single women under 30 earn more than their male counterparts. Overall, a woman in this group earned 8 percent more money, but the discrepancy was even greater in cities like New York (17 percent) and San Diego (15 percent).

The reason for this reverse gender gap is mostly attributed to education. Young women are more likely to have a college degree than young men. Married women, women with children, and women older than 30, however, all still make less than men.

So, what's going to happen when all these newly wealthy, single women hit 30 and their biological clocks start making noise? Well, there will be a whole bunch of under-employed slackers, ready to sponge off of their salaries and provide them with some sperm. So, yes, ladies, it's a trap.
