Most people with economics degrees have taken Econ 101. A modest number of other people have. Some more have learned the basic concepts by means other than taking Econ 101. These are probably not the people complaining about price discrimination. In any case, being surprised when people are upset because they think they're getting inferior treatment and saying "oh, but they should think of the gain in overall economic efficiency" seems like a sign of, well, not having taken Psych 101.
