As someone who is strongly against UBI, and strongly supportive of welfare I can earnestly say people simply not working is not at all the reason I (or most people against UBI in my opinion) are against it.
The reason i am against it is because it causes people more harm than good. People who are in a position where they need assistance need to be given the tools to get out of their situation, and the help to get there needs to be conditional on this (and we should be spending the money that goes with that). Financial assistance should be conditional with mandatory job training or mental health therapy needed to help someone succeed, not just money.
In fact when there are underlying bad habits, as can often be the case, it is possible money can even make a persons condition worse and cause them to sleep farther into poverty.
Not at all, quite the opposite it proves my point and part of the basis for it.
You are assuming my points incorrectly most likely. For example I never claimed UBI wont cause an apparent decrease in poverty, it will, so long as you maintaint he infinite unending firehose of money, people will (obviously) have more money and less poverty. That is not, however, a demonstration that the root cause has been solved, in fact it allows the root cause to get worse and be masked, since your just dumping money on top and not solving the problem, but are effectively masking it.
