It has it's ups and downs.
More seriously, this is a failure of both our education system and industry.
Currently the American education system pushes students towards college at the expense of people working in the trades (or in some cases actively or subtly disparages and degenerates this class of work). Sometimes this is through subtle comments in an effort to focus on moving youth to college as the ONLY solution, when we need a trained work force for all classes of work. Even farming has a huge need for knowledgeable people. (See what I did there...I degenerated farming deliberately to prove my point of how subtle it can be, when I wholeheartedly disagree that it is not skilled. Technology is needed to assist the farmer and their skill and knowledge is critical for our country. But these types of comments, especially in formative years, make it seem like these roles are not important!)
On the other side, equipment and spares are hard to come by. It isn't a huge growth industry, but it is growing and we need to solve some of the problems with supply as well as skills. Some of the manufacturing problems are due to one-off design (for various reasons) and other to JIT (just in time) manufacturing. We also have a shortage of qualified people to machine the parts.
