Below is a very good book that I think many young folks should read. It speaks to the very subject of how important trades are and also how they looked down upon. It's an inspiring book and may help one to understand and be proud of working with your hands.
It also speaks about our youth's narcisism and over inflated ego's... mainly the ones graduating college.

Shop Class as Soulcraft

by Matthew B. Crawford

Excerpt: “The Case for Working with Your Hands”
—The New York Times Magazine
“Shop Class as Soulcraft is a beautiful little book about human excellence and the way it is undervalued in contemporary America.”
—Francis Fukuyama, New York Times Book Review
“Matt Crawford’s remarkable book on the morality and metaphysics of the repairman looks into the reality of practical activity. It is a superb combination of testimony and reflection, and you can’t put it down.”
—Harvey Mansfield, Professor of Government, Harvard University
