It’s from an essay of Mark Twain’s* where he talks about how people’s opinions depend on their social situations – where they get their money from, who they talk to, etc. (Corn-pone was a staple food.) It’s a little like the famous Upton Sinclair line: “It is difficult to get a man to understand something, when his salary depends upon his not understanding it!”

So I take nazgulnarsil to mean that the author’s position is a trivial function of who pays him.
