It gets worse
 

Hmm, not too late for me to change careers. $33/hr currently, but if demand exceeds supply of workers, that price can't hold.

Why would you need a journeyman to fix a charger?

Couple places I worked, the techs were trained to follow a certified process which negated the need for high skill. If they ran across something really intricate/difficult, they called home to the help desk.

Worse case; back in the day, IBM evolved to board swapping until it was fixed. If it was really fubar, they replaced the whole unit.

'electricians'
 

So that's 20,286 electricians, a year, out of a population 336,000,000 citizens.
406- trainees per year, per each state of the republic.
Obviously 'impossible.'

In 1976, during a college field trip, I visited a local manufacturing facility which used computer-aided machining.
If anything went 'wrong' with the equipment, the operator dialed the phone number of the milling machine manufacturer back east. The computer on the other end of the line diagnosed the problem, and sent a message, instructing the operator to change out a particular plug-in circuit board ( of which the factory held in inventory ) to bring the machine back online.
The 'multimillion dollar' mill was back in service within minutes, and never required anyone with more than a high school education to 'fix' it.
In the present day of 'over-the-air' updates 'n such, I don't see a problem.

I switched from letter carrier, to fleet manager, to electronic technician, to traveling area maintenance technician at the post office over the last 2 years. I was going to retire in 3.5 years but had been thinking this new gig is too easy to retire. I could be convinced if it payed about $50/hr including driving time. Thats more than I make now, but why would I leave for less when more time also keeps increasing my retirement? The PO may need a bunch more electricians too with the fleet electrification.

It probably depends on what is failing. The circuit boards and communication links can be back doored, but there are also some dangerous high voltage connections, inverters, and transformers, cooling systems, etc. That would need actual electricians. These things are probably more complicated and dangerous than commercial HVAC systems.

Right now I work about 2 days out of 5 for about $35 an hour so not that interested in being an electrician unless it's for my self.

Aptera and Xbus look better every day. The best plug is no plug.

I don't care much about the money as long as it's reflective of the value added.

Easy gigs bore me to death and I grow to despise them. Doesn't matter if I'm getting paid a ton to do something that doesn't challenge me.

Electricians don't have an easy job. They crawl on their bellies through puddles of water under houses, and tiptoe in rafters in 130 degree attics. It's work to be proud of though, because one has endured the situation and made a thing better afterwards.

About the same rate I'm at. It's not the electrician's wage that is alluring to me, but the opportunity to eventually own an outfit. My personality requires that I'm either the janitor with no responsibility, or the owner with all the responsibility. Middle-management are for people who enjoy being a bully, or incompetent at making the big decisions.

Cant see where they install this stuff in hard to access places. No crawling around under, over or hard to get to. Federal and universal muni Code requires power turn off within 6ft, so it's not a shock hazard. Only major requirements could be some sort of lifting device. Everything else is plug and play with sealed modules because you dont want your service people poking around the innards. Worse case the repair person needs a weeks training doesn't need the 36 weeks electronics course I required for servicing nuke missiles. All the techs I see lately have pictures and instructions they watch on their phone.

So I stand on my original comment regarding service. Ain't rocket science, and I am qualified to determine that.
