I think UBI encourages people not to work, which is a detriment to society. Things like welfare and disability could be adjusted so that increases to these would be targeted to people who need them. Not universally applied like UBI.
I agree hence why I said, it should only be applicable to a time limit so one can get their GED and 2 yrs college. After graduation, they can get a job, save $$ and got to university if they want, paid by themselves. I like that the 'past' experiments' were a success though.
