You're still thinking of it in completely the wrong way. All skilled labor is, is unskilled labor for training, and current labor. Nobody gives a shit who trained who, or where it magically needs to hang.
Training is unskilled labor. The value of skilled labor represents the time it took to train for said labor. It doesn't mean you can throw bodies at a skilled problem.
If you're missing the point this badly, I don't think you'll ever get it.
If the value of skilled labor was equal to the time it took to train there would not be situations where someone was screwed or blessed. My kids teachers have masters degrees I only have a 4-year degree in engineering. Guess who makes more money?
