You lost me when I saw the attempt with a formula. There is no formula and it's pretentious to think you can distill the variables. Try this book: Shop Class as Soulcraft: An Inquiry into the Value of Work by Matthew B.

On both economic and psychological grounds, author Matthew B. Crawford questions the educational imperative of turning everyone into a "knowledge worker," based on a misguided separation of thinking from doing. Using his own experience as an electrician and mechanic, Crawford presents a wonderfully articulated call for self-reliance and a moving reflection on how we can live concretely in an ever more abstract world."
