My guess is this is of interest to us because it sounds an awful lot like UBI. But, I think the key difference is that the money is connected to parents, who presumably have a standard for how it's spent. If E.J. ended up spending it on drugs or other perceived vices, there's a chance the money might be cut off. The point of UBI is that it is 100% no-strings-attached, which has a different dynamic. That dynamic is on…
There's another important difference from UBI, that only a few kids now get this $28k. So being one of them, you can out-bid the others on having a nice apartment... whose price would otherwise rise.
This applies to work too: she could get ahead artistically by being able to write full time. Ahead of the competition, that is, who had to work. UBI wouldn't have given her that advantage.
