Teachers are criticized for low outcome. They pay school taxes, too. The companies that complain about non-skilled workers are the very ones who request tax breaks which remove funds from schools.
My father taught algebra in high school for a couple of decades. He once told me that he was training employees for Ford and Peabody Coal, so, why didn't they just train these young people themselves.
He kept many people in school. He was my high school assistant principal. He moved on to start a breakfast-in-the-schools program.
I have a picture of my father in his rural school. He is wearing overalls and no shoes. He went to college on the GI bill after volunteering during WWII. I now live in a town that boasts a missle manufacturer which is whining about not having enough skilled workers. Refer to paragraph one.
