People also need their lives to have value. We are social animals. As a generalization, there is a strong desire to be (viewed as/able to view themselves as) a contributor to the community.
These don’t have to be linked: we have (significantly!) stay-at-home-parents and philanthropists and retired community workers. But in our current values system, it is often linked - having a job in the household is viewed as a moral good. It might be hated, but it’s at least “contributing” something.
If this goes away, and we have millions completely adrift? With no structure to contribute to? Even with the largest welfare expansion in history, I think we’re preparing for a very turbulent society.
