I have yet to see any evidence that a job guarantee is better than an unconditional basic income, nor that a JG/UBI combo would be better than just providing a higher UBI. Experimental evidence will always sway me though, so I do welcome such evidence being created and published.

What I do know is that JG operates within the mindset we need to escape from, that being paid in exchange for work is the only way of contributing to society, that those who have less ability to work are somehow lesser people, & that automation should be avoided in favor of toil.

It is so weird to me that among JG advocates, the belief is so rampant that people must be paid on the condition of work, or else no work will be done, as if unpaid work doesn't exist, and as if the reason people do that work freely could never be the motivation for doing it.
