It does not move anyone out of poverty, and quite frankly it is abused by a massive amount of people.
It's impossible to abuse UBI, as it's not means tested and you are allowed to spend it on what you like.
Why did they make SNAP all card based and put restrictions on what you can purchase? Because an extremely large percentage of people were not purchasing food for their kids, they were drinking and smoking the money away.
This is right-wing fantasist bullshit. It revolves around the 19th century concept of the "undeserving poor", that people are poor because they make bad decisions, and if only we could make their decisions for them, everything would be better. You can't both believe the idea that wealthy people act in their own rational self-interest, and believe that poor people don't. There are of course some families with social problems, such as alcoholism or drugs that cause them not to look after their children properly. And the answer to that is social wordkers and social services. Not treating everyone who finds themselves on welfare as a child.
Other countries manage to pay welfare in cash, and trust people to look after their children.
Taking from the productive people to give to the unproductive incentivizes non-productivity.
Productivity is a calculation which has labour cost as a divisor. We are heading into a world where the cheapest labour is robots, and most people won't have work producing things. In such a world, people don't have to be productive - machines do. This is a central point - UBI is about a world where we can't even pretend that full employment is possible, or even desirable.
Of course it's good for people to do things. But those things will no longer have to be dictated by an employer, nor be productive.
And to pre-empt your obvious objection... yes there will still be some jobs, and there will be plenty of people who want to do them, because UBI only provides the basics. There are always people that want to work for more than the basics.
