I’m a tradesman. The reason people don’t want to work trades is multifold.From your perspective, why don't people want to work these jobs ?
1. They’re taught the trades are labor, lower caste jobs if you will.
2. High school counselors ignore the trades as a career path, instead pushing kids into college whether it suits them or not.
3. There is a stigma of crusty old farts hazing new people. In part that exists but lots of new apprentices have simply never been told they failed a task and need to redo it. Thin skins, they quit.
