Well, that is certainly true. Those trades need people, but for reasons I can't understand nobody wants to work anymore.
I'll tell you an interesting story. I went into a bar near the University of Kentucky, and struck up a conversation with a fellow who owned and operated a company that made oak table tops. Following on a smart remark I made, the fellow went into a ti-rage in esoteric physics. The owner of the bar wheeled out a damn blackboard for him to use during what became a lecture. It turns out that he held, honestly, three PhDs: Two in physics, and one in math!
Later he told me that he loves to make simple things, the smell of a woodworking shop, and a serious lecture in physics!
A good education supplements life, regardless of your chosen way to make a living.
