If affirmative action has such clear evidence that it works, why do not the Swedish government implement it as a general rule for all their employees? Sweden has a very high gender segregation rate, around 85% of people that has a full time employment do so in a gender segregated profession, and government work places tend to rank at the very top as the most gender segregated work places. If it leads to more qualified employees, which I assume would correlates with their suitability, it would save money and reduce mistakes in key areas like healthcare which then would result in saved lives. A national policy would be a win-win for everyone. A while back I looked if any municipality had a general hireing policy in order to combat gender segregation. So far I have yet to find one that even mention gender segregation as something to consider when hiring new people. There does not even seem to be one that something as vague as a goal to reduce gender segregation.
