Isn't white vs blue collar a latent variable? You have to operationalize it somehow. If you just ask "how blue collar are you?", people's answers will be influenced by all kinds of subjective biases.
I'd argue sitter vs stander distinction also makes this presentation more visceral, memorable and understandable. Collar color would feel unnecessarily abstract and boring.
