I'm blue collar. Formerly a maintenance electrician, now in a similar, but different and less physical job, still blue collar. I was forced to work in a cube for a year, at a desk, and every day was miserable. I am not cut out for office work.
I can see myself being able to do this job to my minimum retirement age (57) pretty easily, but hopefully won't have to.
My preferred way of living would be stay at home wife who takes care of all the household stuff so that weekends are just for fun (or two-man jobs I can't do myself), but, since I'm single and gotta eat, I'd say I have the best job ever.
