I actually think there is something to this. The oldest people tend to be holding tons in wealth and assets, making things like houses unaffordable. People working longer before retirement means that job openings and promotions are repressed for younger people. All of these things mean younger people don’t hit the societal milestones at the times they’re meant to hit them which causes anxiety, depression, hopelessness. These things increase the likelihood of drug use, criminality and suicide.
