The Patriarchy™ was not an immediate hit. Though men were generally receptive to the idea of slippers and martinis, things that don’t exist aren’t the best incentives. Moreover, saber toothed tigers and sasquatches were real. If they ladies wanted to fight them, why not? The men could then spend more time foraging for semi-poisonous fruit and not getting mortally wounded. Some men even suggested they’d earn many more large and shiny rocks if they only employed women. Lower salaries would reduce overhead.
But the patriarchs prevailed. (The patriarchs had a habit of making the women whose mates wanted them to fight tigers smile a little too much. It wasn’t always singles rubbing the feet or feet being rubbed, if you know what I’m saying and I think you do. As there was no internet nor easy mail-order brides, the dissenters had little choice but to agree to the plan.)
And thus the Patriarchy™ cemented itself as the shadow government running all of civilization. Soon memories of past struggles faded and women became content to spend their days running the household while the men continued narrowly avoiding death in order to bring home delicious wild boar bacon. Men developed better tools to procure said bacon. Life became idyllic, mirthful, and fruitful.
