We’ve already seen decades of welfare programs wreak havoc on low income communities.
The Welfare trap, going back decades shows that it is almost impossible to get out of it because the way benefits roll off you end up losing $1.5 in government "assistance" for every $1 you make in wages, so people can not escapse
Plans like the Negative income tax would be far far more humane and actually help reduce poverty
I find myself supporting UBI more because it avoids a lot of those pitfalls (instead seemingly moving its weaknesses to some more obvious and awkward areas, a trade I definitely would take in the long run).
Most welfare programs, including UBI, don't disincentivize people from sitting around doing nothing and don't incentivize people to work if they can. Even worse, many welfare programs actively disincentivize people from working, effectively trapping them in the welfare program.
I also think it would be good to implement an incentive to employers to report to whom and how much they pay to discourage people from working under the table.
