The struggle between men and women benefits their divide et impera strategy, because playing people off against each other while maintaining an irrational authority is their main talent.
But in the case of SnapChat and Uber (and many other tech companies), the founders were literally (and archetypically) both Frat Bros and Tech Bros, who set the tone and culture for the entire company, and rampantly hired other Frat Bros from their own Frats, at all levels of incompetency.
Incompetent nepotistic job placement is basically what frats are all about. (Once you get past all that other stuff that Andrew Moisey documented.)

This is still just meaningless name calling, not made any better by the fact that it's so entirely US specific. It certainly isn't even remotely close to an explanation for the global preferences both genders express for different jobs. As I assume you're aware that in fact most jobs aren't gender balanced, most are dominated by one gender or another?
