It's also funny because blue collar work is / can be ridiculously well-paid, in part thanks to the union's efforts.
They are outnumbers ~2:1 by the blue collar workers I know who make that kind of money by working for themselves or by making themselves so indispensable to some employer that the employer pays them well above market to retain their experience in a non-union environment (e.g. the maintenance guy at a factory who's been there forever and a half and knows exactly why everything is the way it is, this maps pretty well to a lot of the highly paid "architect" positions that a lot of tech BigCos have).
I'm not sure how these situations map to a salaried workplace.
Yes I know this is just an anecdote.
