As much as the majority of people don't want to acknowledge this, it is true.
In the bigger picture, men are generally builders and warriors, women are reasons for building and combat, and men will engage when the reasons are worthwhile.
Quickly building becomes a society, and combat becomes protection, and the reasons are still worthwhile.
Looking a little farther, women are also similar to society, culture, and nation, men will support and protect that which is worthwhile. Note that in western languages major constructs (nations, societies, ships, buildings ect) are assigned the feminine pronoun for reference.
Men build and protect entire civilizations for women.
The big problems come when a large number of women become unworthy of the effort, there is much less motivation to produce and protect. Finally, if a man is not allowed to keep enough of his production for himself to make his life bearable, the societal construct will not be maintained or protected, then we start over.
Romantic, isn't it, I expect to hear from the gals shortly.
Hey, I’m a gal and I totally agree with you.
