Able-bodied? Sure. Able-minded? Not quite. There's a huge surplus of middle-age men more interested in pointless office politics and political propaganda than doing good work, conducting themselves respectfully, and maintaining competence. And a dearth of the hardworking, skilled variety.

This isn't just a training problem, it's a cultural issue.

Praising charlatans like Scott Adams, and worse, failing to recognize their lack of ability and their motives is another cultural issue.

Ultimately, the reason we have so many unemployed is because we're stupid. We suffer from a cultural stupidity partly the result of longterm political propaganda campaigns by less-intelligent politicians and industry leaders who can't gain support any other way (because they are also stupid). If America wants to slip back to the level of a third world country in terms of political systems and the average education of the citizenry, a higher unemployment rate is just par for the course.

We have people unfit for training.

As an aside, how can the American workforce maintain world class competency and compensation? We need to interact with the best in the rest of the world. Bringing them here and giving them the option to stay in a safe, fair environment is best. On the flip side, engineers need to believe they are being compensated fairly for their efforts, and not take so many pains to prevent the industry from developing better ways of doing things.
