Though I grew up with the sons and daughters of factory workers (some of whom went into the factories themselves after high school), I never worked on the line with them. I tried to; many of them had new cars and were making somewhere between $18-$22 an hour -- and this was in the late 70s! Of course, with some exceptions, that kind of bread for that kind of labor isn't there any more. Instead, I worked on a garbage truck and made decent money, though the labor was truly back-breaking.
When I moved to Michigan just over a year ago, I could have gone into more white-collar "creative" areas but chose not to. I had enough of that crap when I lived in New York and wanted to re-connect with my roots (such as they were). So there I was, a published author, reviewed in the Times, working as a janitor in a boutique mall. Through this gig I got other blue-collar freelance work, and now I get calls for all manner of labor (just got one this morning from a woman asking me to shovel the mounds of snow that are sagging her roof). So in a sense I had a "choice" to go this route; but I do need the money, and if it isn't this it's something else. I still have to work.
What I find amazing at the working level is the control employers have over labor. I mean, drug tests are mandatory here (and since I refused to take them when applying for certain jobs, I lost out on better pay); and the prospective boss can ask you about your personal life, and so on. You are degraded before you are hired! The sad thing is that many workers put up with this -- not by choice, I'm afraid, but out of need.
