Zinn: Well, you know, it would be manifestly difficult to believe in magic rings unless everyone was high on pipe-weed. So it is in Gandalf’s interest to keep Middle Earth hooked.
Chomsky: How do you think these wizards build gigantic towers and mighty fortresses? Where do they get the money? Keep in mind that I do not especially regard anyone, Saruman included, as an agent for progressivism. But obviously the pipe-weed operation that exists is the dominant influence in Middle Earth. It’s not some ludicrous magical ring.
And there is more of that jazz :)
