I have worked in manufacturing for over 30 years. 20 years ago we hired people right out of high school and they had a desire to improve their place in life. Some moved on to a better paying job, some worked up to lead, then supervisor, and the up to management. The high school graduates we are hiring today have zero practical job skills. People we hired a year ago know no more today than they did eleven months and three weeks ago. Most have to be retrained after a long weekend. If their phone won't tell them what to do, they are incompetent. The greatest generation is dead or dieing, there children are retiring. I don't think we will ever have the labor force to bring the manufacturing jobs back. Twenty years ago maybe a quarter of hires could convert inches to centimeters, now three quarters don't even know how many inches are in a foot.
