From time to time I've read articles about the dearth of (semi)skilled workers in machining, exploration, etc.
Factories clamor for skilled workers. The pay isn't bad either. IIRC, 60-80k/year is not unusual. And if people are willing to move to ND and join the oil shale rush, apparently unskilled workers can pull in low six figures.
I recall an anecdote of a truck driver who lost his job. He entered some program which would teach him some skills to make him marketable (something like welding).
He quit midway through because he said it didn't fit his lifestyle of freedom (ir something to that effect).
It kind of struck me as odd and somewhat selfish. I mean, I recall taking on really crappy jobs (like at oil change places) when I could not get anything better. I didn't like it. Yeah, it cramped my style, but it helped me get thru college and eventually university.
