I'm convinced that UBI would make the world significantly better for everyone. I'm sure it wouldn't outright solve problems like homelessness or poverty - financial literacy is still a thing, and people still fuck up or end up in bad situations that they can't control - but al of these problems would be made significantly less impactful.

I also understand why the ruling classes of the world will never allow it to happen without a fight. If you aren't dependent on your job... Then why stay in a job with poor conditions? Why stay working for a company that doesn't care about you? Why tolerate poor pay? Suddenly workers have 1000x more bargaining power in every discussion with their employer... And frankly a lot of people would want to work part time, which is going through start to impact on company's ability to employ enough staff at all.

Obviously they have a way out - providing employees with a better quality of life, benefits, good pay, work life balance, etc.... but all that costs money and they hate that.
