Hmm. I smell a whiff of agenda, but here goes, my take on this based on personal experience and observation.
Women are expected to work to support themselves, fair enough. It's supposed to secure financial independence and autonomy. However, social conditioning is such that certain roles are considered more appropriate and attainable for women, despite progress. Paid caring and adminstrative roles are still considered traditionally women's work because they are seen as natural extensions of both women's nature and their experience at home. If women have siblings they have cared for, or elderly relatives, well they can "choose" to do that as paid work because it's a role that needs to be filled, but because of that attitude the pay is less, and these jobs are regarded as easier by the ignorant. Women may be seen as innately more nurturing and trustworthy. (See threads on this site where nurseries employing male staff are viewed with suspicion).
Many women don't actually have much "choice" in the job market as they will be juggling the responsibilities of home life, often caring for children, elderly relatives and supporting husbands and partners who are career focused (as manly men should be).
Fortunately these days women can choose to be more career focused. It requires sharp elbows, single mindedness and sacrifice of many aspects of family life, or even having one at all, and hats off to those who do forge that path and shine brightly. But many who go that route are still marginalised and sidelined in favour of men who don't bugger up HR by needing maternity leave or flexible hours around child care etc. Even though these things are enshrined in law, savvy employers will keep their profits in sight and find ways round it.
How many scientific breakthroughs / innivations have been celebrated with male names attached, only for it to be revealed in later years that some brilliant woman did all the leg work and had their hard work nicked at the finishing post?
I think asking the question "why don't women choose high paying jobs" is pretty disingenuous, because no individual can really choose that outcome entirely. They may hit a sweet spot through a combination of hard work, good luck, being in the right place at the right time etc. You may as well ask why doesn't everyone choose to become a millionaire? As if it's down to sheer force of will. Which it might be in some cases, but a proportion of wealthy people have got there through sheer ruthlessness and dodgy dealings, and there are a great many men and women who prefer not to trample over other people for the sake of pure avarice. I'd rather be poor with a relatively clear conscience than knowing people had suffered for my success.
It's extremely complicated, but thinking about it makes me wonder if women are conditioned to embrace collectivism and men to pursue individualism. Both sexes have biological impulses to procreate and the choice whether to do so, but a woman's choice and the consequences are broadly seen as hers, while men only have to shoulder the financial burden, which even then should be shared equally between a couple despite structural inequality.
Out of curiosity OP, what is your opinion of "evolutionary psychology" ?
And also your references to biotechnology and Catholicism make me wonder what your personal beliefs are, and how they tie into collectivism and individualism.... I'm very interested to know now.
