It's a question I ask myself often when I see the disrespect Americans have for people in jobs they also consider essential. I have other questions for myself like, "how would I truthfully explain this to my mother?". If the answers make you feel shame, then that probably tells you something.
I wasn't aware I was making an argument. I asked a question (which was apparently loaded) and gave my thoughts. It's my experience that American society in general disrespects working class people - it's pretty clear from the stagnant wages and multi-generational political movement to suppress unions, so I understand why parents would not want their children to join that class.
