Personally, I think that the idea of continuing school for a few years, immediately after high school, then becoming an instant 'professional' is one of the ways our society has gotten off track.
There's something to be said for some seasoning, experience, and maturity before adding another layer of 'education.' There's even some merit in the idea of actually being able to DO something.
There's no shame in learning a trade - indeed, I would be leery of any architect, engineer, or designer who hasn't ever actually BUILT anything.
I also object to this idea that you get your degree ot journeyman card, and your quest is over. Balderdash! It's just beginning.
So, let the boy earn his journeyman card and be proud! Then encourage him on to the next step.
