That stable environment was always more or less a myth.

Some people live the 'on rails' lifestyle, others never find the tracks, some get kicked off after a few years.

At its best it's a tool for helping make sense of life and society, but it can also be a destructive myth that leads to resentment and anger in those who end up somewhere else, like they're entitled to this outcome that just wasn't in their cards. Easy to get lost in that darkness and fail to actually make something of life.
