“Women want RESOURCES.”
They want SECURITY. In the past that meant the biggest and strongest man. In this society it means a man that has proven he can earn and achieve.
A woman’s instincts tell her to choose a man who is successful at bringing home the bacon so that their offspring will have a good chance at survival.
RESOURCES == SECURITY
She can also divorce at any time and take > HALF THE RESOURCES.
She usually will not divorce until she already has ANOTHER RESOURCE already lined up.
