In general, the technicians in an electronics company have an average IQ well below the graduate engineers. Many of the questions and responses on this forum suggest a lot of technician grade people are here. My experience with amateurs interested in electronics is the interest spreads across all IQ levels, and there seems to be a high proportion of amateurs here.
Congratulations on reviving the EEs -vs- Technicians discussion.
Your comments come over as elitist in the extreme, as well as poorly conceived.
There are many reasons why people choose to become Technicians rather than go to University & get an EE degree.
Foremost among these are lack of funds, responsibility for a young family or ailing parents.
To just say in effect:- "Techs lack the intelligence to become Engineers" neglects the large number of people who have, after some years in a Technical role, gone to University & done just that.
Others have gone on from Tech work to found businesses, do Degrees in some totally different field, or become experts in again, some other esoterica.
I have worked with very good & quite poor EEs, & have seen little sign of any innate intellectual superiority in either case.
