That's what I am thinking too. It will be interesting to see how people who have only seen UBI their whole life will behave. In a summer job as a teen I worked at a government welfare agency. Some of the clients were third generation welfare recipients and you could definitely see that they had no idea how a job works because they had never seen anybody who held a job for a long time. They would just skip work for a week without telling anybody or be insulted when the boss told them what to do.
A UBI experiment will probably need 50 years or more to determine what the long term consequences will be.
