Have you ever considered that that is just an improper and wrong world view.
I agree that it is theoretically the wrong way to view the world. However it is how the world works, if you treat a cop like some people treat a service worker like a waiter you could easily be shot.
Are you actually out here judging people based on their jobs and or economic backgrounds and using that to decide how you interact with them
Personally, I do try avoid ranking others via social status but it is pervasive in society. If you don’t understand that people unfairly judge you based on your income, class, gender, role, or any other factor, it makes dealing with issues like sexism and racism a lot harder.
