I don't want another CEO or businessman ever running for POTUS. Ever. Perhaps, it is alright to have a cabinet position but not POTUS. Ever. Anytime the U.S. has chosen a businessman for the position, it's been an unmitigated disaster.
I think Yang has some points on automation and jobs but I still think his answer is too simplistic. I do think, Universal Basic Income could be a temporary solution to help people who inevitably fall through the cracks whenever the country transitions into another industrial shift but it most countries who try it, only have it temporarily. I'm not sure how it can be made sustainable on a permanent basis but as a temporary "patch" for people of working age, especially people who are chronically un and under-employed, I think it could actually be a viable idea.
That would definitely need to be factored into any Universal Basic Income plan. Color, gender and age discrimination all work negatively against job applicants, it's not just about automation. I do agree that he tends to over-simplify aspects, he could benefit from talking to grassroots and community organizations who have studied these issues on a granular level to gain more nuance. I don't even pay attention to his following, really, although I've noticed a few that I've seen seem to have gone quiet lately. Maybe those are just a few of his POC women followers.
