Exactly.

Who can't?

So?
By the way, just googled, entry level electrician apprentice with zero experience (you are required to do that for some time to get your license) gets about $30K. That's not a lot, but that you can do with almost zero training, and it in several years it is significantly more.

Maybe they can be paintworkers then. 38K of income is not as lavish as the life of electrician, but that's should be good enough who cannot get an electrician license.

Truck driver, nurse, carpenter, crane operator, plumber, car mechanic, firefighter and so on. There's a lot of thing you can do with little or no investment.
> Like in the US now average electrician makes 70K a year. That's a lot of money. And anyone can be electrician.
I would not consider electricians as an example of poor people. And no, not anyone can be an electrician. It takes training and licensing, and many people can't jump those hurdles. (Not to mention the fact that if everyone became an electrician, very few of them would get any work.)
