Here&#x27;s the money quote (literally):<p>&gt; &quot;maintain the sharp boy&#x2F;girl product division&quot;<p>You&#x27;re assuming what they&#x27;re doing is unprofitable and irrational. But a majority of families with two or more children have children of opposite sexes and a cultural taboo against different sexes sharing the same toys means parents need to buy more toys. It isn&#x27;t hard to believe that this strategy is profitable on net.<p>So it&#x27;s really showing the other thing -- not that the market isn&#x27;t efficient, but that it can be efficient&#x2F;profitable for the market to be sexist.<p>But that makes the analogous thing in tech that boys are encouraged to be programmers and girls are encouraged to be nurses. Which is a thing that happens predominantly in schools and at home and it isn&#x27;t clear how the software industry would be a beneficiary of that -- which is perhaps why we hear many calls to do something about it. The profit-seeking behavior is to change it.
