What about making people profit and enjoy life without having to push propaganda that this or that work they contributed to make them worth having them alive?
The premise that if they are not highly pressured to produce something people will just do nothing or only wrong things is such a creepy one.
Universal income or something in that spirit would make far more sense to get rid of this concern of having people not to worry about being able to live, whatever occupation they might chose to pursue on top of that.
The main issue is that the meritocratic narrative is like the opium of the most favored in power imbalance. Information can cure that kind of plague according to literature[1], but there is no insensitive to go on cure when other will pay all the negative effects of our addictions.

If I would need to choose only between UBI and high taxes on the rich I would choose the latter, because it would reduce the risk of entrenching the differences or giving too much power to a few.
I find more important what is the society's perceived "success" in life. For US (one of the two countries in the study), as a foreigner, I perceive that "success" is considered to be "the self made man". So people feel valuable if they have stuff. I doubt UBI will fix that - and unhappy / depressed people is not great, even if they are not homeless and starving.
In other countries "success" can be considered also about "just" living a nice life, enjoying food, or friends, or sport (even if you are not top). And these countries will try to offer paths to some stability, even for the ones that are not the greatest, such that as many people as possible in the society feel good. Makes a nicer environment for all...
