It's work, you'd better know math, some geometry and trig but it pays well. I retired in 1999 at $24 per hour and all the over time I could stomach.
It's not a desk job and you might get dirty from time to time, alternatively, you can sit around and moan about not having a job in your area of expertise.
I like your suggestion and agree with it.
People make a mistake when they think a college degree entitles them to a job in the area they studied. In some cases, like engineering, thats true. For many other areas, though, its a mistaken expectation.
For me, the purpose of a college education is the education itself. So, get your education, then get a job out on the shop floor and learn your trade. If you're smart, and work hard, in ten or twenty years you'll be running the place, or you'll have opened your own business.
I'm all in favor of liberal-arts degrees as preparation for life. Just plan on getting a real job when you get out, and don't be afraid to get your hands dirty.
My question is, would they take somebody with the classroom credits but no actual experience?
