Still not sure what to believe on this issue.<p>Some points of discussion are (unrelated to article):<p>1. If women were 25% cheaper than men while being as competent, wouldn't white/male capitalists trip over themselves to only hire women to increase their profits?<p>2. Women are less likely to negotiate salary and assert themselves, as women in general are more agreeable than men. Is this behavior based in biology or is it social construct?<p>3. Women tend to choose lower paying jobs, such as teacher, caregiver etc. In general women tend to care about people, while men care about things (STEM). Again: biology or social construct?<p>For example in Sweden, which is doing it's best to increase gender equality, sex differences between men and women maximized <a href="http://jamda.ub.gu.se/bitstream/1/833/1/scb_eng_2014.pdf" rel="nofollow">http://jamda.ub.gu.se/bitstream/1/833/1/scb_eng_2014.pdf</a><p>So perhaps occupation differences are healthy and natural. Of course, in Sweden engineers don't earn 300% more than teachers, so it's not a huge problem like in the USA.<p>The logical solution would be to increase pay in women dominated professions. But this kind of thing spits in the face of capitalism.<p>It's a tough problem to solve, and I still have no idea how to go about solving it.<p>EDIT: Additional explanations
