Gene Wolfe, a really great writer, discusses the Lord of the Rings and their influence on him and the influence he believes they should have on society at large. It's a conservative viewpoint, but not a bad one. I particularly liked this:
"Philology led him [Tolkien] to the study of the largely illiterate societies of Northern Europe between the fall of Rome and the beginning of the true Middle Ages (roughly AD 400 to 1000). There he found a quality -- let us call it Folk Law -- that has almost disappeared from his world and ours. It is the neighbour-love and settled customary goodness of the Shire. Frodo is "rich" in comparison to Sam, though no dragon would call Frodo rich; Sam is poor in comparison to Frodo, though Sam is far richer than Gollum, who has been devoured by the tyranny and corruption of the One Ring. Frodo does not despise Sam for his poverty, he employs him; and Sam does not detest Frodo for his wealth, but is grateful for the job. Most central of all, the difference in their positions does not prevent their friendship. And in the end, poor Sam rises in the estimation of the Shire because of his association with Frodo, and rich Frodo sacrifices himself for the good of all the Sams."
