laura k explains more clearly than I am able, why I hate haggling. Hopefully deep transparency will make the Iron Law of One Price a fact and not just a promise, but more on that in my upcoming post on deep transparency. For now, laura has given me another rallying cry: No bargaining but collective bargaining! Commenter allan adds:
People who are shy or hesitant are penalized for who they are. They may end up paying more for items and also earn less at their jobs.
I refer to this phenomenon as the aristocracy of push.
