There is definitely a balance between "I am comfortable never working" and "I am uncomfortable never working." There needs to be something appealing about working, and there needs to be something unappealing about not working. Balance in the United States is definitely skewed towards maximum (fatal) discomfort for not working. The real argument is that moving forward, the incentives for working won't go away but the opportunities will - so the tech college job keeping your brother out of LoL is much less likely to be available, and much more likely to be taken by people who want it more. There is already a massive group of mostly-men who play video games rather than contributing to society. That group is likely to grow. An entrepreneurial sort would figure out a way to tap that resource in such a way that you can profit off their labors because as a group, it's going to get bigger before it gets smaller, UBI or not.
