Shop Class 2.0: Rethinking High School to Accelerate Electrification

It's led me to a lucrative career in programming, but now all my hobbiest time is actually spent learning the same hands-on skills I would have gotten in shop class, I love doing automotive repairs, I even learned how to fix my own AC system, and want to learn to weld.
Electrical is the tricky one because it's the one with the most consequences for mistakes. I wish there was a "electrician lite" night school or something.
Although they do often tell me "oh I could never actually do that, I'd lose my mind". Which of course many of us do :)
You can learn a whole lot about electricity by working on small low voltage projects like that without any risk of harm to yourself.
Brian: I'm a **in' idiot because I can't make a lamp?
Bender: No, you're a genius because you can't make a lamp.
Brian: What do you know about Trigonometry?
Bender: I could care less about Trigonometry.
Brian: Bender, did you know without Trigonometry there'd be no engineering?
Bender: Without lamps, there'd be no light.

And if you're in the US and a healthy adult, you're probably not going to kill yourself if you take a zap at 120V/15A.
Wiring mains circuits is about craftsmanship and the ability to repeatably follow technical rules for low probability events that were nevertheless "written in blood". Tinkering with electronic circuits is not going to get you the engineering rigor you need to come at mains circuits from first principles.
You certainly can learn DIY house wiring safely as its own thing! The point is that they are just completely different skillsets, and you shouldn't be extrapolating confidence from low voltage circuits into mains wiring.
Also no, while 170 volt mains voltage (US residential peak voltage) is not likely to "kill" you, the actual risks are things like house fires from short circuits and intermittent connections. If you're doing anything where you're worried about getting "zapped", you're doing things horribly wrong in the first place.
For most household wiring tasks, turning off the circuit at the breaker box is the main safety provision. Using a wire nut properly is a bit tricky but not the worst thing in the world, and I don't trust a rushed contractor to tighten a wire nut any better than myself.
> Using a wire nut properly is a bit tricky but not the worst thing in the world, and I don't trust a rushed contractor to tighten a wire nut any better than myself.
This ties right into my point though. Low power circuits generally don't use wire nuts, and even when they might, they don't use thicker solid wires generally used for mains wiring. So you most likely learned wire nuts as their own separate skill, rather than from low voltage circuit work. My point is you've got to learn all those mains details in their own right, rather than thinking it's just like low voltage/power wiring.
(I totally agree about trusting yourself versus a rushed contractor! Emphatically yes - please do learn to DIY! My point is about the learning path to get there)
For mains it's not the 120V zap I'm particularly worried about, it's the possible fire that occurs months later while I'm asleep because of some rookie mistake I made (connection that gets loose and starts to spark or something), that endangers anyone in the structure.
If I could have all the danger upfront and while I'm actively working on it (like woodworking), and limited to just myself, I'd be much more comfortable.
I disagree. Woodworking is WAY more dangerous.
I have had exactly one mishap working with eletricity over the years. Somebody wired a piece of industrial equipment backwards (neutral as hot) and I got the shit shocked out of me.
I have had quite a few near misses in woodworking even while being amazingly aware. I know of no old woodworker who has all of his fingertips.
This video is about woodworking injuries gotten by YouTube streamers (CAUTION: Graphic!):

The one I never thought about was the final one (the table saw accident). It was a dual combination failure. He took an injury on his right arm which drew all his attention which then caused an accident with his left hand.
Yeah, I'm a big believer in safety equipment, even when it's inconvenient, after thinking about that one.
But there is also hand tool woodworking as a hobby. Much less risk. I won't say none (a falling chisel has no handle), but you are much less likely to suffer a life changing injury.
When woodworking, I'm aware of the spinny bit and can watch a quick video on how to use the tool safely. And it's only a danger to myself (or anyone in the very immediate vicinity), while in active use.
My fear about electricity is the hidden dangers, or how things can seem to work fine up for hours/days/years until they don't and melt/start a fire, and then my home can go up in flames while myself and my family are asleep over something as trivial as a loose connection.
Not every job needs to be (nor can be) a desk job, and with the advent of AI tools, you'll still have many hands-one roles in the field. Much of the difficulty of getting solar and home battery storage (like Powerwall) is because there is such a shortage of electricians.
Also, before the pedants go finding nail hammering robots, it’s a simplification to make the point that there will always be room for the trades in the real world.
We had shop classrooms on site all kitted out to teach kids welding, carpentry, and fabrication skills, and even had the old shop teacher still on staff. Admin just didn't want to teach it anymore, and all that equipment sat gathering dust. It would have been sick to offer a beginner's welding class as a study hall alternative.
As a student on the honors track, all of this was completely inaccessible to me due to academic requirements. For example, to take Calculus as a senior, I had to have already complete 4 years of math classes (meaning doubling up one year). Calculus itself was a "lab" class, meaning it met 3 days a week for an hour, and 2 days a week for 2.5 hours. That left zero time for anything not "academic".
As an adult, I use algebra and geometry frequently, and have to resort to Youtube to learn the plumbing, carpentry, and light electrical work I use almost every weekend to maintain my home. It would have been nice to have learned this at a younger age, so that I could do things efficiently and at a higher quality instead of fumbling around for hours.
This article does address the push for all kids to college. Read comments at [2] as well.
Very useful comments about the barriers to entry: [3].
My own biggest concerns would be:
1. Popular anti-union perception: bad for recruitment, and bad once you're in.
2. Need to be in good financial shape by 40 so you don'
I recently read a long thread explaining how hard it is to apprentice to an electrician, and how only the people at the top who own their own companies are really making good money. Too much work too dig it out.t ruin your body.

The doublethink I hear on unions is crazy.
I have multiple family in the trades that are un-unioned and their statements are along the lines of:
- They constantly bitch about how horrible unions are
- Oh, {insert company here} workers voted to unionize? the unions just gonna fuck 'em over
- All the people they started with who moved to unions are retired with well funded retirement funds and they really should have gone union when they were young.
I wonder if the average person thinks that something like a Tesla charging station is something that's manufactured somewhere far away from them and just plugged in to a the nearest power line. "We have electricity everywhere so it's just a matter of time" mentality.
We drove kids to college under the guise of "you'll be fucked if you don't" while simultaneously sounding the alarm on climate change but didn't think to try and connect the two problems to anticipate the solution 30 years ago?
There are historical examples where electrification was accelerated, e.g. FDR New Deal programs like Rural Electrification and the WPA, but that would entail a complete restructuring of federal government priorities, increased taxes on the wealthy, redirection of military-industrial budgets to domestic infrastructure, etc. Seems unlikely in the current political climate, where oligarchs run both parties like sock puppets.
Quality of life at work means things like having to travel, volatility of schedules, health risks from the work, quality of coworkers, etc.
Volatility is are you getting paid a salary every 2 weeks, or are you exposed to more fluctuations in landing jobs, and dealing with customers who do not pay.
Maybe the situation has finally turned a corner where an office/white collar job is no longer a no brainer.
A neighbor kid I grew up with, struggled with acting out in school. His home life was massively disfunctional. However, he loved to tinker and play with all things mechanical. I think an apprenticeship in high school would have been life changing for kids like him.
