I concur that due to the fact they tend to be overeducated posh people do have that feeling of grandeur. They seem as ifthey are infallible and do not make mistakes. Their excuse is usually their SAT scores. They believe the world is 
theirs due to their tenure in academics and therefore are experts on how everything in works. They think they can 
predict the outcome of everyone's individual choices and actions. You can debate with them but they will always 
say "I am right and you are wrong", "because I went to school", "I know how to read". So on and so forth.
