[specialist]

My millenial aged kid became an electrician. Mostly residential. Mostly remodel (vs new construction). The type of clientile that want fancy lights and legit security systems. And now early adopters of solar, batteries, and EVs.

He'll have plenty of work for decades.

It is hard on the body though. Which is why he stayed residential. So he claims; I would have guessed new construction commercial would easiest physically. Especially if you specialize (eg elevators).
