In the US in recent years, around a third of all open management positions have gone to women. My research over the last three years has shown that the trend is going in the same direction at all levels. And by the way, it's not necessarily that the rise of women is causing the end of men - it's more the other way around. An increasing number of men are failing during their education, losing their jobs and then not managing to get back on their feet, so women have had to step in. The driving force here isn't feminist conviction, it's economic necessity.

It's a fact that within the space of a few decades, women have achieved a massive shift in the role they play - in the way they act in public, and in the way they have conquered areas of the working world that were until recently considered a man's domain.

Green jobs - those are jobs that feel like new economy jobs; they do require some training.

Evolutionary psychology tells us that men, especially powerful men, feel invincible and entitled to spread their seed, and that women can't resist the scent of masculine power. Women, by contrast, are said to be more altruistic and collaborative, seeking power so that they can share it with others.

Marriages are failing, and mothers are raising their children alone. Many women would rather remain alone than marry a man who can't contribute anything to the family's income.

Men need marriage more than women do. In fact, they need it to survive.

As we get used to women in power, we are likely to discover that they behave much like powerful men - vain, entitled, always looking for more.
