Earlier quoted context omitted.
You can absolutely have a career in construction, as I know many people who have. The challenge is health. It's a very demanding line of work where you have to carry weight, wake up in the early morning and work in the cold. People don't want to work like that. It's very hard on the body and you're broken when you reach your 50's.
It's almost like that problem would be partially solved if the US had a system where you could get healthcare without needing it to be tied to full-time employment.
When you are in your 20's. You fall from a ladder, break some bones, you heal and get back on your feet one year later. When you are in your 50's, you are more fragile and less resilient, same thing happens, you might never be able to work again. It's brutal.
