Ah, you're right; of course the medically related job should be taken over the other, all else equal.
I have to admit that the rest of your post made me laugh a little. "added insights into their world... their points of view... peeking into the working class world." Their world is my world, aside from the fact that I'm currently a student. I don't exactly come from what you would call a "college family" and I've worked (and currently work) blue collar jobs since before I could drive.
I'm not implying that you sounded condescending or anything, it just startled me that you would assume that working a blue collar job would place a college graduate out of his/her element. After I thought about it though, it makes sense. You sort through who knows how many applicants every year, and I would imagine that a rather small percentage of them come from lower income backgrounds. So I understand the assumption.
