As I stated in my previous comment, it's because other high paying industries stopped being sexist against women, and then the women that would have been pushed out of those industries and into CS can now study and work in the field of their choice. Nowhere did I write that "they don't need the money", and I even said that they were choosing other high paying fields once medicine, law, etc. stopped enforcing overtly sexist policies against women. Discussions are more productive when you engage with what other commenters are writing instead of your own inventions.
Obviously if a choice is starving vs CS, most women would prefer CS. That’s the choice for many women in Iran (most equal country in CS) or India. That’s not choice for most women in US or Europe. We are talking averages here - obviously there are a lot of women much more motivated by money than average men.
Such a convenient explanation... CS is one of the highest paid professions, and women are taking advantage of lack-of-sexism and choosing to stay out of CS... because umm... they don't need the money? You should consider speaking at the Grace Hopper Conference, because there's lots of women there that haven't been told this truth.
