This is what is being talked about in many European countries: applying quotas to get more women on boards of companies and in manager positions. The exercise has worked well in Norway where quotas implemented not only got the 40% required of board members being women, but they even did 4% better and are now at 44%.
Time magazine just published an article on the matter that I urge you to read
And why wouldn´t women be close to 50% of those taking decision at a higher level? Especially when many fields and universities graduate more qualified women than men at this time. It also has shown itself that there are different "men" and "women" qualities that can be found in either sex...men are known to take more risk and be more financially-oriented while women are often careful and think more about social consequences. Of course these qualities can be found in either men or women although they're often called a "feminin" or "manly" side. Up until now "manly" qualities have dominated the business world, as well as politics and even the media.
Things are going to change and its about time. Qualities that before were attributed to women and were shut out will now become more and more in demand at decision level. But for women to want those positions, it also has to be adapted to people's lifestyle. Less women are ready to sacrifice everything for their career and I believe that will be the case with men as well. People in the west will want to balance work, family and personal time, in a Scandinavian style in the years to come. Unfortunately quotas, or at least the threat that they will be implemented seem necessary for things to change and countries such as Spain, France and Britain that have women making up just around 10% of top boards, are seeing the necessity to change this with legislation. But its not only in business the change has to happen.. a non-scientific observation tells me that women are much less in politics, express themselves less in the media and still have lower salaries than their male counterparts. This has to change and now. We need a true Revolution, but not only in the boardrooms of top companies.
