It's a stark difference to basically every other point in history. This'll probably be seen as how we look at smoking today. It shouldn't be any surprise that when both parents are mostly absent and taking high stress jobs, the children won't be as mentally healthy. Mentally unhealthy kids become mentally unhealthy adults, and that leads to this downwards spiral we see in society what with mentally ill people going into law enforcement and management. Even with all the new pills, they're not curing the root causes.
