> companies like Google are doing exactly that by promoting policies to bring in and retain women
The problem is that they do it in the extreme. They want to achieve 50% of male and 50% and currently that distribution is not real, there are much more men that women in technology. So they have a positive discrimination for women to get a position even when there is a man that fits better, so they can achieve the 50/50.
If you want the best people and the pool of candidates is 70/30 you cannot have the best candidates with 50/50. You should have like 70/30 that is something proportional to the pool of candidates.
This leads to the question why there are less women than men in technology. Is it discrimination, oppression, a free choice?
