A very good point. Women don't go to STEM jobs because they get sufficient compensation in work that they like more, on the average. And it's easier to do what other women do.
That factor hasn’t stopped women from becoming e.g. doctors and lawyers.
Just 50 years ago, very few women did that, because discrimination (e.g. for healthcare in America, gender-based discrimination was only banned in 1975) and culture norms.
But now it’s pretty close to 50/50 gender ratio in these areas (females are 47.3% of law students in 2007, 46.7% of medical students in 2013).
Yes, we can conclude that structural discrimination of women in law and medical students has largely gone away. Why does anyone think that STEM subjects would somehow retained such discrimination?
I consider it more likely that now women do what they want to do. And that is in many ways a good thing.
