> we also expect white collar workers to be treated differently than blue collar workers.

How should we treat someone (a Korean in this particular case) who doesn't wear his collar ? "Sorry i struck you, but you didn't wear your white collar. Better luck next time". What if a blue collar worker wears a white collar ? Is he excepted from humiliation ?

Treating people like animals makes you an animal.

are you unfamiliar with the term blue collar/white collar, or are you being sarcastic? i don't mind the sarcasm, i just want to make sure i understand you correctly.

you would not treat animals like that either, btw.
