I propose that a 20 year old phd will have many options open to them, including taking an easy job and spending their own time on an interesting hobby. If a person can be educated with the information and methods to succeed, they should be better able to interact with the world. Slowing down a person with the potential to finish formal education so that they can spend more time being spoonfed isn't going to improve their chances.

Also, if one chooses a grinding slog of a job, it's better to be a 20-year-old phd. Presumably, they're getting paid well, and they can start on their early retirement fund from better positions vis a vis a generic 20 year old.

I am unconvinced by your argument.
