Male sedation hypothesis might have a part in it as well.

The "Male Sedation Hypothesis" proposes that digital stimuli like video games, pornography, and social media are sedating young men, reducing their tendencies for status-seeking and reproductive behaviors, which historically might have led to instability in societies. theorizes that these digital interactions provide men with titrated doses of what would traditionally drive their social and reproductive pursuits. For example, men receive reproductive cues from pornography and camaraderie or status in video games, leading to reduced real-world interaction and aggression. This is potentially creating a less volatile but more socially detached male population. Williamson perceives this as a mixed blessing; while it prevents disruptive behaviors, it may render these young men less effective in real-world situations that demand assertiveness or direct action

So the gist of it is basically that in prior times like this, the discredited young men have taken it to the streets, assembling in groups of other similar men and start causing trouble by breaking windows and kicking grannies. However, we're not seeing this now despite the record numbers of such men and one hypothesis for why this is, is that those men are instead withdrawing from the society into their mom's basements and spending their time playing games, watching porn and smoking weed.
