Jeff Bezos, Bill Gates and Mark Zuckerburg never need to work another day in their lives. Are you arguing they are miserable, self destructive, have lost purpose and will soon die?
People don't need a Sword of Damocles hanging over their head threatening them with homelessness, loss of medical treatment and hunger solely because they didn't find purpose in life.
How is being miserable and self destructive and losing purpose, as a worst case scenario, worse than homelessness, drug addiction, loss of friendship, family, self respect, health and medical treatment?
I mean, I don't see the connection. Are you saying that unless people are literally threatened with homelessness, starvation and death they won't find purpose on their own?
