Yeah I get the part where it says you aren’t encouraged to achieve because you can only have x amount of money, or if you get a job, you will lose x benefits. Where as the UBI you can still have that, and you can earn more by working. There would be nothing saying you won’t have this or that. The idea for current welfare is that it’s based on need, which was adopted after the great depression. Also taxes on the rich were in great amounts and the economy boomed like never before or ever again. Which many people did not use welfare at the time too because they had no need because they had jobs because the system was working.
But the economy hit a few more recessions and growths since then and the recovery has been diminishing every time. Meanwhile the people on welfare has only increased. So if it’s based on need, and say the economy gets pooped on again (which it undoubtedly will) what is the point if nobody can use it when they actually need it? Especially considering it’s actually discouraging people to work instead of a system that might encourage them to be more productive? Because we all know society, friends, family, we all encourage each other to succeed. I think that is something we all want. We just have it rough because the welfare system is like a poverty trap.
EDIT: tl;dr I think it would work if adopted and people continued to encourage each other to do better.
