There seems to be a common fixation on objects "modeling the real world" with the counter argument for classes being that they don't model the real world. True, there isn't a physical chair class in real life(philosophically, there aren't even chairs), but there is a common abstract idea of what would describe the function and attributes of a chair. Granted, it differs a little from person to person, but objects themselves are all different in some way. As far as I can tell, in most OO languages, there's no reason why classes must use inheritance, though I am certainly willing to be schooled in that regard.
