Women make around 78 cents to the dollar that men make for doing comparable work — and pay around six times the price men do for comparable things and services, from deodorant and shampoo to hair cuts and dry cleaning.“I don’t see this going away anytime soon, because the dialogue in our culture is that men and women are different — we call each other the ‘opposite sex,’” says Nicholas Guittar, who studies gender pricing as assistant professor of sociology at the University of South Carolina Lancaster. “Gendered pricing disparities will persist despite the presence of increased gender equality in society.”But perhaps, since the gender binary is melting away as our New Language of Gender report argues, it is gender fluidity that will impact this pricing disparity. After all, how can you create an unfair "woman tax" if the category of "woman" no longer exists, or is at least ambiguous as a category. Gender fluid products/services and pricing could become part of a brand's positioning. The trend we've been tracking — Blurred ID, resulting in gender fluidity — will impact this unfair woman tax. Until then, "ladies," shop in the men's aisles.Daily updates on the new language of gender – download now.
