I've written on this blog about a billion times about how it is that when the economy goes into the ditch, there suddenly becomes all of these articles and "studies" to show how "smart," meaning those in the top one percent of income earners, are jettisoning their traditional roles because they are "selfish" and will live to regret it.
I.Q. tests don't actually measure much of anything except help shrinks in diagnosing people who may need special education services or help them get disability. Furthermore, many of these elite women have "careers" only because they are trust fund brats to begin with and have a lot more freedom to do what they want than those of us out here who had to slave and work for every goddamned dime and STILL have our security kicked out from under us by sociopaths who call themselves "bosses." Unless you are in the financial elite, you don't have a lot of control over how your life turns out.
Getting back to this idiotic study. It sounds like the person who came up with this is scared the elites aren't having enough babies to balance out the kids of the riffraff.
Of course not, but the elite of the elite have the money, thanks to manipulating the law or stealing from other people outright, to control the masses.
