[eucyclos]

Whoever said anything about middle class? Ubi is the poverty level, it could never be anything else.

As for people not being occupied, the theory is that since ubi doesn't stop if you find employment, it would lead to less idleness than the current means-tested social safety nets. In test cases though it seems to depend a lot on culture, Finnish communities saw no difference in employment while Indian rates of business formation tripled.
