In the animal kingdom, females are actually far more useful. Take lions for example. Lionesses both rear cubs AND hunt for the pride’s food. And they don’t complain doing it. They are also very dedicated mothers and will sacrifice anything to protect and nurture their young.

Same if you see those national geo videos on baboons. The only time they slack off or act unloyally is if the main male isn’t doing his part in protecting them and breeding. Otherwise they are dedicated to helping keeping the clan safe and in balance. much for what human females have to provide.
