But Morthoron
I never mentioned exclusivity 
And I did wonder if the Cabots were still only talking to God
I did state that mythology did tend to concern the great and the good so I am not sure why you are picking me up on that... :S
Yes it always helps to have friends in high places but in some cultures changing your station in life is just not possible. It was possible in the Shire.
However I certainly agree that there was too much separation for a racial class divide at the end of the third age. Even the men of Gondor have little contact with the Elves, the Rohirrim regard them with suspicion tinged with fear and hostility. Only the rangers have much to do with them and they are regarded as vagabonds by the "respectable" folk of Bree.
