Beyoncé says women still don’t — yet. The “Run the World (Girls)” singer acknowledges there is work to be done to make things equal for women, and she explains why in a short essay titled Gender Equality Is a Myth!

“It (gender equality) isn’t a reality yet,” writes Beyoncé in the essay, which is included in the annual Shriver Report on women and gender equality. “Today, women make up half of the U.S. workforce, but the average working woman earns only 77 percent of what the average working man makes. But unless women and men both say this is unacceptable, things will not change.“

Beyoncé argues that people need to stop believing we have reached gender parity and that it’s time for men and women to work together to make a difference.

“We have to teach our boys the rules of equality and respect, so that as they grow up, gender equality becomes a natural way of life,” writes the mom to Blue Ivy Carter, who recently turned 2. “And we have to teach our girls that they can reach as high as humanly possible.“
