The efficient market hypothesis kind of falls over in the real world, though. There's _many_ fields where it isn't trivial or even possible for new competitors to just arise from nothing.
Well, if marketing in a given field is genuinely a waste of money then eventually a competitor should be able to enter the field and beat the incumbents by spending less on marketing. There are some fields where the cheap generics win out, but there are others where they don't.
