How many guesses do you need?
Here’s a small sampling:
“Women May Earn Just 49 Cents on the Dollar”
“Gender pay gap is worse than thought: Study shows women actually earn half the income of men”
“U.S. women earn half the income of men, new study finds”
“The Gender Pay Gap Is Way More F***ed Than You Thought”
The last one is from the always measured and reasonable “Jezebel,” in case you were wondering.
But what these articles are forced to admit is that the study finds the gap is caused by women taking more time off from work than men.
As Iowahawk noted ages ago, if capitalists could actually hire women at half the cost of men for the same work, men would never hold jobs again.
