If we look at their lives outside of work, can see where you're coming from (as mentioned, a few of my current and past roommates worked blue-collar jobs, and couple of them really had a tough time financially, and one of them emotionally). But if we're talking about the job themselves, as mentioned, seems like most blue-collar jobs are less demanding, and is stable at many levels, and doesn't require much training.

Yeah, at least to me in this thread, seems like we were referring to jobs themselves, not their overall lives.

But, I do agree, if we look at their lives overall compared to white collar, it seems like it can be just as stressful, especially because of the lack advantages growing up (growing up in a stable financial household, education, resources...).
