UBI in theory: The payments will free up the poor's resources to improve themselves instead of of exhausting them all on necessities.
UBI in practice: The payments allow the poor to lay around and do nothing, ending up more impoverished for it.
Y'know Sam Altman, you didn't need to spend millions of dollars on a three-year long study to figure this out. I could've told you this is exactly what would happen, because the redditors who shill for UBI don't really hide the fact that they just want to jerk off and play vidya all day for the next thirty years of their lives.
