Another thought on the UBI... how would it have shaped your financial and career planning if you knew that you'd have enough for basic living after retirement, no matter how long you manage to survive? That's one of the big concerns - how much money do I need to sock away for the unknown remainder of my existence?

You never change things by fighting the existing reality.
To change something, build a new model that makes the old model obsolete.
