Contrary to popular belief, women's elaborate grooming and dressing are often not for men, but are intrasexual signals of aggression, dominance, and social status aimed at other women. An attractive woman signaling this way is seen negatively by rivals.
People are often unaware of the ultimate evolutionary drivers for their actions, such as attraction or competition. Consciousness frequently develops post-hoc justifications, meaning individuals don't know the real 'why' behind their behavior and simply invent a plausible story.
As a competitive tactic, women advise female rivals to delay having children and prioritize their careers more heavily than they would for themselves. This serves to subtly suppress the reproductive success of competitors under the guise of helpful advice.
To win the evolutionary game, one can either increase their own reproductive success (the gas pedal) or actively inhibit the reproductive success of rivals (the brake pedal). Both strategies increase an individual's net reproductive success relative to the population.
For a reproductively suppressive ideology to be an effective competitive strategy, some women must genuinely adopt it (the 'losers'), reducing their reproductive success. This creates a relative advantage for the 'winners' who promote the ideology but do not follow it themselves.
Strategies that make mating more difficult—such as devaluing marriage or masculinity—create a hostile environment. While this hurts everyone, it harms those with lower mate quality more severely, raising the bar for entry and creating a relative reproductive advantage for the elite.
In subsistence societies, women invest all resources into their own offspring. Only in affluent, safe societies do women accrue enough surplus resources (time, energy, capital) to make investing in the suppression of rivals a more adaptive strategy than investing further in their own reproduction.
By branding traditionally attractive masculine traits like dominance and aggression as 'toxic,' women can manipulate the mating market. This sabotages rivals' ability to select high-quality partners by steering them toward less desirable mates, thereby inhibiting their reproductive success.
Female competition involves suppressing rivals because female reproduction is capped and vital for population survival. Male competition is a 'sprint' to maximize personal success, as suppressing one rival is futile when a few men can easily repopulate and pick up the slack.
When a civilization shows signs of decline (falling birth rates, vulgarity), it signals the 'end of the game' is near. This intensifies female reproductive competition, as the goal becomes ensuring one's lineage is part of the small 'founder population' that will seed the next societal expansion.
