I wish I could hope for UBI as genuinely "U". But I remain convinced that human nature (and wrong assumptions about lazy people) will ensure it doesn't happen.

I'm pretty sure I could set myself up to survive on €1000/month. My pension if I ever get there would be more - but I suspect it UBI ever happens, then state pensions will cease to exist and people will just get UBI instead (though since Germany gives you a pension kinda based on what you earned over time, up to a not-dreadfully-generous limit maybe it wouldn't)
