There is no such thing as a useless profession, which makes it silly to be disrespectful toward any job at all. Very often, the attitude toward others depends on the family a person was raised in.When I was in elementary school, I made a comment that went something like, “he’s just a janitor” and my dad, who was a pretty upper-class man, set me straight about looking down on people. It’s something I always remember and appreciate.
