@hightor,
Interesting, and I'm not arguing re what you say.
My own family was nothin' if not interesting, and I won't try to put a world of observations here, but I will add about my husband and his brother. They both got full scholarships at a good and also nearby university.. parents were poor and so was south LA. Husband had worked his way through as a handiman (part of how we bought the house, his savings and mine), and got a masters in theater. Bro nabbed an architecture degree, but also went to Trade Tech, or similar name. Went to Africa teaching carpentry, etc., in the peace corp. He's been a long time head building inspector and still likes his job, has always remodeled where his family lived, rebuilding the houses.
In my own time, having been part of a landscape architecture firm or had our own, I am sure the mason earned more than I ever did... and deserved it. Many well read people like building places or things, and beginners are learners.
My point? I think we need more trade tech schools. People might be happier.
