I'm pregnant and you are the father.

Well, I agree with you entirely, but it doesn't look like you actually disagreed with me. I'm not saying that they are 'evil' to extract resources from men (over the history of our species, that is, I'm not talking specifically about now). I think it was actually essential given the sex-specific roles that were adopted, and those were successful roles, making us one of the dominant species on the planet. We are inherently a species that lives in small tribal groups in a hostile environment. It doesn't look like that now, with vast urban civilizations, but that has happened very recently. Women did most of the foraging and looked after the children (particularly the young children, older boys would progressively spend more time with the men). Men hunted and defended the perimeter against predators and enemies. Given the time that human children need to become independent, it was inevitable that women would have to forgo the arduous and potentially dangerous tasks, which in turn got the most valuable food (meat). So it was reasonable to share out tasks, and for women to evolve means to get men to give them protection and share the high-value food. Nothing wrong with that at all, but the result was that women learned to be manipulative, to use their lower sex drive to get an advantageous position (they were always the most privileged class in society, when you looked beyond the obvious). In today's society this is not to men's advantage, because women have abused the privilege. They no longer are so willing to fulfill their role as wife and mother, and therefore it makes sense for men to scale back their investment too. Part of this is recognising when and how women manipulate.

It is also because women are less physically powerful than men that they became naturally Machiavellian. They used a subtle, indirect form of power to get what they wanted.

As for women being more childlike, yes, and to me (when it isn't actually childishness) it is an attractive feature. Women can spend hours with young children doing the same thing over and over and not get bored. On the other hand, many native tribes understood that there came a time in a young boy's life when he needed to be separated from the influence of his mother and learn to become a man. That process no longer happens.
