i agree with you on the theme of the end of the movie, it will be hard to sell that to your everyday joe six pack, wayyy too hippie(for lack of a better word)for they're mind.
but just think if we were a utopian society and worked as one we could be in different worlds collecting resources and socializing with whatever is out there,
I do not think it can ever happen. It is the nature of man to put himself before others, with profit (what's in it for him) as his first motive.
You only have to observe a 1-year old child to see how it manipulates adults in order to get what it wants (food, attention, love, etc.)
Even religion, which in it's purest sense does not involve money, it still involves profit. You believe in Muhammad, or Jesus Christ, or Joseph Smith, because you believe you will be BETTER OFF for doing so.
