You are assuming that the world is well ordered and that all things will balance like that, but it isn't. People don't see those jobs as options, they aren't even aware of the opportunities, and there is social stigma against being in the trades. Even if you make a nice living in the trades, you will take a hit to your social identity, making you less attractive to others. That's how toxic our culture is right now. People don't value good work anymore, they value branding and image. And we are going to collapse because of it.
