The real problem that the industry faces is that a significant number of Cabin Crew, in the USA particularly but not solely, have been taught/encouraged/trained to behave towards passengers in a bullying and threatening manner, if and when a passenger questions any instruction, including one to give up a seat, get off the plane for no good reason, and so on. Cabin Crew sometimes appear unable to distinguish between the instructions they must legitimately issue for the safety and good conduct of the flight, and instructions which have some other purpose, such as accommodating over-booked passengers. These same people are far too fond of making dire threats of legal and police action.
This tendancy needs to be stopped right now. So does the tendancy for cabin crew to hold their customers in contempt, spurred on by threads like the one that used to exist (perhaps it still does) on PPRuNe, sneering at foolish questions and remarks by passengers. Most of us could start and populate a hilarious thread about the things that Cabin staff sometimes say. (EG, I heard a Ryanair FA reassuring a nervous passenger; "Don't worry, if both the wing engines stop, there's another little one in the back." She was absolutely serious; I checked with her.)
