Well obviously. They study 14-16 hours/day so that they don't have to be minimum wage workers at fast food chains, because that's the only option they'll have if they go to a "shit" school.
With a UBI, the bottom rung will no longer have to work those humiliating minimum wage jobs. They'll have the freedom to pursue their own interests, whether that be entrepreneurship, the arts, etc. Those corporate wage slaves working 14 hours/day will probably work less, maybe even only part-time. Even if nothing changes, at least the option to walk away without having to stress about money will be there.
That being said, UBI isn't the solution to all of society's problems. I just think its the most urgent policy decision that needs to be implemented due to its simplicity and massive implications.
