Lots of backed in assumption in here.
The way we designed out current society makes unemployed people some kind of pest, it's not glorified, quite the opposite.
But that's not a god given rule, nothing obliges us to follow that path, especially if (big if) AIs/robots take over most things.
If anything you're flat out wrong, automation moved people from stable and fulfilling jobs (small companies, family companies, life long carriers, &c.) into more and more precarious situations (minijob, student jobs, faceless corporations, hashed carriers, &c.)
Productivity shot through the roof while wages stagnated
PS: I've been unemployed for large chunks of my life and had perfect meaning, I was productive, learned stuff, created stuff, enjoyed nature, got in shape, &c.
