The thread about the girl flying around the world got me wondering why people are so concerned about percentages of men and women in certain fields, particularly percentage of women involved. It seems like it is more important to people that the percentages be as near to equal as possible instead of having the different fields (aviation, etc.) open to anyone who wishes to pursue them. If it's really important for percentages to be equal in "traditionally male-dominated" fields, why isn't it important that female-dominated fields have balanced percentages? Why don't we have campaigns so men know that they can become nurses? After all, less than 10% of nurses are male. Or teachers or librarians or speech therapists? I'm all for careers being open to everyone, but just don't understand the fixation on percentages.
