We already discussed the reasons plenty:
1. Insane Dating Standards
2. Toxic Feminism
3. Females only go for top 20% men
4. Gen Z dudes are socially awkward, focus on themselves for the time being
or have simply given up
5. Financial cost
It will get worse tho, the future is:
1. Even crazier Dating Expectations from Women, as women will get far more powerful in the future and land better paying jobs
2. Lots of Guys that would have the opportunities still will decide to be volcel due to danger to themselves (being robbed, being accused of xyz, being shunned socially) or simply due to evolving a lower Testosteron level and thus not being sex interested
3. Guys turning towards different sexualities: asexual or hetero for the most being.
4. Economical decline, Dating or hell just going out to a Club, Festival, Bar is getting more expensive then ever. Even the Dating Apps technically dont function for men because you dont see the likes on ANY App without paying. On top of that women will become way more financially independent, you already see a rise of "We dont need men" women now, this will become a new Feminist movement of pure Volcel women - in South Korea this already exists called 4B.
5. Automation and Digitalization will turn future Generations of men and women even more apart. The technologies will essentially have the effect that Ted Kazynsky predicted 40 years ago, where everyone will be too distracted from each other to even care entering a relationship, thus even just "situationships" will vanish.
6. New Copes: Whether it will be Virtual Reality Brothels, Artifical Super Intelligence Cyber Waifus or new forms of Drugs, men AND women will eventually care even less about each other.
Ultimately, it is to say that we will expect a massive rise of "Incels" and Single Mothers in the future and when Gen Z is old, Society is collapsing eventually.
