Right now, we're at AT LEAST 30% inceldom, and it's only getting worse. We have a lot of blue-pilled incels in denial, but that won't last forever. Once a normie improves himself in every possible way, then spends years STILL being treated like a turd that won't flush, he has no choice but to search the Internet for what the hell is going wrong, and find the black pill. The black pill WILL become widespread; that is inevitable.
Once that happens, men will see the futility of careermaxxing/betabuxxing and buying expensive status symbols, making it harder to fill high-level jobs and reducing the market for luxury items. The economy will tank hard.
As men abandon the higher echelons of employment, women will find it even easier to get there (affirmative action already made it easy), so betabuxxing will be even less effective as a mating strategy. Since women generally lack the drive and ability to excel in the more demanding jobs, the GDP will suffer from that alone.
But worse yet, who will do the physically demanding, dangerous, and dirty jobs in sewers, off-shore rigs, etc.? The only reason to work a job like that is to provide for a family. So if men can't have families anymore, good luck filling those positions.
This clearly isn't sustainable. The government or society will have to somehow reverse the damage done by the sexual revolution and dating apps, and it's hard to see how that would work. Things will get ugly.
There is one bittersweet upside for the angrier among our ranks; once things really deteriorate, life will suck for everyone, including the women who treated us like something to be scraped off of their shoe.
