This will be unpopular, but: what if an uncomfortably large part of the population just really doesn't have anything economically worthwhile to offer in the modern context? Nobody wants to say that, but if it's true, then something like a UBI or dole (even granting the author's problems with it) is all we can do short of mounting a massive Plato's Cave-like conspiracy to convince people they are doing something usefu…
I agree with you, at the same time I believe that this is a failure of the educational system. The current educational system is fucked up. One of the main problems is that it creates "good students" as opposed to people who grow up to contribute to society.
I hated this about high school and university. You are forced to regurgitate what someone said as opposed to developing your own opinions.
