>This machinery has to be operated by somebody, and people can be trained to do it. It takes people willing and able to do it, however.
Sure, but it's on the companies to make the move and hire people, not the people to go and beg to volunteer for them. This isn't the old days where you walk into a factory and give the manager a firm handshake and then you get the job.
If a company is willing and happy to train anyone who is up for these jobs and will pay them properly, then there will be people who will do it. But if they are still going to reject people based off credentials or experience like usual, then that's their problem if no one wants to do the work in a crisis like this.
