As people get older, they often come to realize that any job that puts a roof over ones head, food on the table, and allows quality time with friends and family, is meaningful work.
There is some truth to this, but I think this way of thinking is overly simplistic. From a material standpoint, any job that can provide for you and your family's needs is "meaningful" since you can't really have a meaningful life without having basic needs provided for. From a spiritual standpoint, however, I think it is detrimental for someone to know that their job is largely pointless or achieves no tangible outcomes in the world. I think this same criticism applies to UBI and other "end of work" ideas, since a person with no job is likely to suffer from the same lack of purpose as someone who senses their job is BS. People are intrinsically wired to want to do work and make some kind of difference (even if that difference is just knowing that you helped manufacture 500 cars that day, dug a ditch that will be used for some useful purpose, whatever).
The typical UBI proposal is not trying to end work at all, and wants a big majority of people to keep working.
The typical UBI proposal will create enormous inflation and end up transferring more wealth to landlords with zero net positive social impact.
