I think what kind of work you enjoy varies from person to person. I do fix things with my own two hands on occasion--there is some car work I am knowledgeable enough to do, and I enjoy building and repairing computers. But by day I do software, and I find it a very challenging and engaging field. I like being a "knowledge worker."
But I would agree that it's not for everyone, and it requires a set of critical skills that many people may not even be capable of developing. Any "one-size-fits-all" approach to workforce development is going to end in failure, which is why I have always been opposed to shipping out industrial base overseas. Our economy should be more diverse, not less. Pushing everyone into knowledge jobs only ensures that most of the people doing them would rather be doing something else.
