In a vacuum, perhaps that would be the result.
But we're not in one, and the US certainly isn't a place where you can just do what you truly want/love to do and everything else will work itself out. It's a very competitive atmosphere and job market, and needless to say most people don't get to do the job they actually want - and instead are steered towards a job closer to satisfying what they need (income/success/etc).
If we all lived in some socialist utopia where choosing a job/career had no effect on your income, means, living situation, how you're judged/treated/viewed, etc, I would bet money on gender-roles still existing. Do you really believe that every job would be 50/50 male/female across the board? From lawyers, to social workers, to nurses, to military, to stem?

EDIT: Reading your latest post seems to indicate you agree with my last paragraph, but you just feel as though sexism is 'rampant' and a major influence in the current state of affairs. I agree that it exists and again agree that it needs to be fixed/addressed, and also agree that acting like the low representation of women in STEM isn't at least partially do to that is ridiculous... but I don't agree on it being 'rampant.'
Interestingly enough, the unemployment rate of women vs men with an education in STEM is actually also lower for women.

So what is being implied with ‘sexism is rampant’ here? Because women that ultimately pursue the field are getting hired (and more often than men).
So to me, that means that you would have to believe that the sexism is in the way they’re raised and the educational system… which to me, comes down to a different topic than the popular implication that it’s the workplaces that are causing the main issues here.
