Interesting question. My perspective is that blue collar is a frame of mind rather than a type of job. Consider this a compliment to most audiophiles: it doesn't seem to matter one whit. Love of music is a big equalizer.
That being said, my life has been one of engineering design and sales. I choose now to not work for anyone except myself. Maybe that makes me red, white and blue collar.
