Many years ago, a friend of mine was in the business of repairing 2 way radios, for police, commercial fleet trucks, etc. I noticed that he only worked alone, but was always complaining about having too much work. When asked why he never had any help, this was his reply.
You have to have electronics training etc. in order to fix radios. Those who are smart enough to fix radios always want that corporate "lab" job. Nice, clean, inside work. This job requires field work. Imagine having to go fix the radio in a cement truck!
My friend was always in big demand, and made big bucks!
Now look at electricians!
More and more states are requiring stringint training and certification. Many who are smart enough to learn it would rather go for that, "lab" job. Nice, clean, inside work. To be an electrical engineer or the like.
Causing a shortage of field electricians! Making us worth more. Supply and demand you know.
