Who is "we"? Who is "all"? Does this include migrants and undocumented aliens who do the dangerous jobs for low pay with no labor protections or civil rights? Or would they be excluded from the basic income? If they are excluded, and have no rights, but continue to perform the dirty jobs while the rest of "us" relax and benefit from their labor, how is that different from the system of chattel plantation slavery?
I take your point, but it's not slavery. A basic income isn't meant to preclude anyone from working. If it existed and undocumented workers were removed, those jobs would have to pay a wage sufficient to entice someone who doesn't need them for survival, or we'd have to go without those services.
