So forcing people to either get a job or be poor is for their own good, then? Just because you don't agree with how people chose to spend their time in a very nerve-wracking situation? This sounds very condescending.
A large number of retirees find themselves in this bucket as an example - if it happens there, why would it not happen no matter the life stage?
I hope to switch you a bit from problem-finding to problem-solving mode.
You have identified some risks, great! Now let's qualify and find solutions for theses in order to move forward. For instance: - assumptions check: young people adapt quicker than older people, so the retirees may not be representative of the others life stages - solution proposal alpha1: education could teach people to look for purpose instead of teaching them a job
What are your solutions to the issues you've raised ?
