There's a definite difference between fine line checkering and coarse line checkering then you have lazer cut and pressed checkering UH ! same with engraving styles from masters vs lazer engraved maybe pressed engraving, a blind man could tell the difference. Being a doctor is fine same with a dozen other professions except politicians. If you have a skill or 2 or 3 you can fend for yourself till the rest of your days. Take a kid right out of cnc machine training and then put him on an old school Milling machine or Lathe and see what happens. I need you to go fix or build this one off part for an old vehicle or whatever could be a combine , tractor, diesel truck, etc and then get a dumb ass look because he doesn't know how to weld, can't set up a machine tool doesn't have the apprentenceship under his belt, doesn't have the working knowledge to know what type / strength of metals to use, etc. The people that can do these types of work and others are worth their weight in gold. I always tell young people if they ask the question pick a job you like that will always be there for your life time, such as police , fire, medical, old school welders, machinists, one off fabrication, carpenters, construction, pumbers, electricians, tin benders, and the list goes on, they cannot go wrong because these jobs are not going away anytime soon. We live in a throw away world it breaks just toss it , until something breaks and you absolutely need that part and it ain't made anymore, now you are going to pay big bucks too get one made or fixed. Case in point I was looking at a fine old Mauser 98 non-military hunting rifle that had claw mounts but the rings were missing. $750 bucks to have them made and fitted I could have bought the rifle for less, so I passed on it. Not many people use these types of these old school German mounts anymore other than African dangerous game guides and a few others or if you can afford them and something you like. To be successful does not mean going to an ivy league school, A good trade school and maybe learning 3 needed trades and you are set for life. Farming and Ranching is not a bad way to go a lot of work.
