Think of how stupid the average person is, and realize half of them are stupider than that.
We still need plumbers/electricians/carpenters/mechanics/welders in this country and those kinds of jobs should pay well enough to put a family in the middle class.
They often do. I remember years ago reading about a shortage of tool and die makers and that journeyman (basically just out of tech school) were getting jobs for like $150k a year.
The biggest problem I have seen is that high schools teachers and councilors push the 4 year degree as the only way to get ahead and that no one should get a 2 year degree or learn a trade if they want to succeed. While they are correct in that a high school diploma basically ensures that you will live in poverty working minimum wage jobs hoping to get promoted to overnight manager they miss the point that you need to have skills. Skilled labor is what is needed and it does pay well. One of my buddies used his army benefits to go to the tech/community college near me and learn how to be an electrician. He now earns enough that he can support his family on just his income but is saving up for a down payment on a house. I have another fried who went and learned carpentry and makes a good enough living he can live like a college student working about 6 months of the year with hiking and camping in the summer and skiing in the winter. Hell I even use the tech/community college near me to learn new skills every couple of years since they do offer courses in the practical instead of the theoretical.
You know, the difference between this company and the Titanic is that the Titanic had paying customers.
