You are correct of course. My comment was kind of all over the place without any clear idea - I just wanted to illustrate that anxiety can also be triggered by the feeling - real or imagined - to not belong. Maybe mixing up class/privilege kind of misses the point as you said there are probably enough well off people full of anxiety. It was just a situation I vividly remembered and as such it's difficult to convey without context and maybe just unfair.
