As long as UBI covers basic living expenses, then yes I would support it. Capitalism, as it exists in the west, is not sustainable and if it continues as is, there is probably going to be massive employment issues within a generation as common working people without specialized degrees and can't afford to get them will be unemployable due to automation, AI and robots completing most common labor jobs cheaper and more efficiently.
I know the pushback against UBI is that if you take away the need for people to work to live, most people won't work... and honestly I'm okay with that. I doubt there would a be serious decline in people seeking work because if you can still earn extra income for luxuries and nicer things over what UBI would cover... why wouldn't you? And those who are content to sit at home or not work, is fine by me. Because I've worked with a lot of people over the years who only have a job because someone told them they needed a job. They were miserable fucking people to be around and we were more productive the days they called in sick or skipped. Some people should be paid to stay the fuck at home, and society would be a better place for it.
