Women are almost half the workforce.

They are the equal. In fact, they are breadwinners in four out of ten families. In 2015, women made 80 cents for every dollar earned by men, which is a wage gap of 20 percent. Women receive more college and graduate degrees than men, yet on average, women continue to earn considerably less than men. How is this possible? Women are just as educated, capable, and ambitious as men.

While the number has gone up one percentage point from 2014, the change isn’t statistically significant. Because the increase is so small, a mere tenths of a percent, it doesn’t amount to perceptible change. According to the U.S. Census Bureau, the earnings ratio hasn’t had significant annual change since 2007. The gap has narrowed since the 1970s, due largely to women’s progress in education, their workforce participation and to men’s wages rising at a slower rate. Still, the pay gap does not appear likely to go away on its own. At the rate of change between 1960 and 2015, women are expected to reach pay equity with men in 2059. But even that slow progress has stalled in recent years. If change continues at the slow rate seen since 2001, women will not reach pay equity with men until 2152.

Women earn less than men in nearly every single occupation where there is sufficient earnings data to compare. Although women are consistently earning less in nearly every profession, they are higher educated across the board. Though men lead the population in primary and secondary education, women lead for enrollment in tertiary education and completion in the highest education attainable. So most people would ask at this point, why aren’t women making more?

Generally, at least 66 percent of America prefers a male boss over a female boss, according to Gallup. Only a startling 5 percent prefer female bosses. This directly correlates to unequal pay among the genders because the American public does not prefer women to be their bosses. Thus, women are not in a position of power in the workplace. What America is saying is that a man should be in charge, and boss statistics confirm this opinion. So not only are women generally more educated, they aren’t in high-earning positions at their work. To make matters worse, women are treated differently than men in the workplace.

“Discrimination is not as it was before; it’s often harder to see,” says Caryl Rivers, co-author of recent book “The New Soft War on Women.” Rivers went on to explain in her interview with the Business Insider that although men cannot physically hire a woman because of her gender, the old-fashioned mindsets ingrained in some men subtly shows what they think. Rivers also explained thirteen different ways women are treated differently in the workplace during the interview.

One reason described was that if a woman is assertive it can be seen as aggressive. Sonya Rhodes, Phd., a physcotherapist and author of the new book “The Alpha Woman Meets Her Match” says, “Whatever women do at work, they have to do it nicely. But the more you back off, the more they don’t take you seriously.”
