Maybe I'm misunderstanding you, but neither of those outcomes sound like failures? They sound like a net positive for society. New mothers get to spend more time with their children, which has a ton of societal benefits, and teenaged boys decided to study more, and become more educated, something that also helps society out a lot. I admittedly didn't read the entire link yet, but both of those sound to me like a positive outcome of UBI, or at least neutral.

It sounds like you understood. I find the disconnect between the summary above and the quote below really funny. Almost as funny as explaining the joke here!
