The Soviet pattern is reproduced today in places like Iran, where many more women study engineering.
Meanwhile, in Scandinavia, the traditionally-female professions like nursing are even more female-dominated than in the USA.
The trend seems to be: The freer the society, the less women are entering the tech workforce and the more they choose traditionally feminine work.
This even applies in the time-trend in America, where women in tech has reduced significantly since the 80's, while feminism has only become more dominant and wealth has increased.
Food for thought.
Since I do not have firsthand experience with being a woman, my information comes from talking to women computer scientists and engineers from my school CS program and my workplace, and listening to their firsthand experiences dealing with sexism in the industry. Their opinions are diverse, but generally are in support for more empowerment of women/minorities in the workplace, so I generally support their agenda. Personally, I enjoy working in a more diverse workplace, anyway (long explanation for another day).
In Soviet Russia during the Cold War, I believe boys and girls were both encouraged to study math and sciences, which resulted in a fairly even gender representation in the career, and neither gender was better than the other on average. Food for thought.
