That is quite a literary interpretation. I think the dream expresses much deeper truths through the metaphors. The ending ends that way because the producers clearly wanted us to question as to which is reality. Remember when he says do not create places from reality into dreams as that is the best way to lose which is reality and which is a dream. Also, when he meets his older self and tells him he has to jump. That indicates that the "reality" on which the film begins is not really reality, that his wife was probably right. But how can she be right when the spinner does stop spinning and yet in the end when we are brought to the same reality it does not stop spinning? This contradiction is supposed to be there as it communicates this entire confusion as to which is reality and which is an illusion we have created for ourselves. Speaking of its applicability to the real world it speaks of brainwashing, propaganda, and formation of our own perceptions, how we can through them create a different reality and be lost in there, yet also struggle to find the real truth. The film, through the metaphor, communicates perfectly this entire confusion and it ends with such contradiction because ultimately we as humans and our thinking can not acquire perfection as to what is truth. We are blind in the end to inconsistencies within our illusions, hence the always spinning spinner. Its a good film, but in the end I think it is really rubbish. The subject is awesome, but it does not go deep enough. The ending is too subtle. There probably should have been some sort of almighty intervention like in the ending of Don Juan for it to become a classic. To allure in the end that there are great forces out there which we depend on and only through taking a leap of faith in ourself can we acquire reality.
