Every jobs program has a huge training and education component to it. This stems from the tightly held American ideal that we are all equal and we can all be interchanged.
Nothing is farther from the truth.
Anyone who lives this side of a hole, and doesn't work for the educational establishment knows that there is a large portion of the populace that is as dumb as a doorknob. These are the folks who have been hanging on for years at jobs that the could never quite accomplish. Your group of workers has several of them. Hell you might even unwittingly be one of them.
No amount of training and education can fix dumb. It goes through to the bone. Those are the jobs that we have lost. Bolting on the same part in a car factory is better done by robots than by humans. Watching skeins of yarn in a textile mill the same.
The jobs that used to support the economy in production are going, going, gone. Vanished by the invisible hand of global wage arbitrage with the cost savings going straight into the pockets of the plutocracy. They won't come back under the current system of cheap plastic crap and the consumer as a target.
