Tyler Cowen, a Star Wars fan, has blogged an elaborate theory about the Jedi — "The public choice economics of Star Wars: A Straussian reading" — essentially being a bunch of useless dicks:
The core point is that the Jedi are not to be trusted:
1. The Jedi and Jedi-in-training sell out like crazy. Even the evil Count Dooku was once a Jedi knight.
2. What do the Jedi Council want anyway? The Anakin critique of the Jedi Council rings somewhat true (this is from the new movie, alas I cannot say more, but the argument could be strengthened by citing the relevant detail). Aren't they a kind of out-of-control Supreme Court, not even requiring Senate approval (with or without filibuster), and heavily armed at that? As I understand it, they vote each other into the office, have license to kill, and seek to control galactic affairs. Talk about unaccountable power used toward secret and mysterious ends.
3. Obi-Wan told Luke scores of lies, including the big whopper that his dad was dead.
4. The Jedi can't even keep us safe.
5. The bad guys have sex and do all the procreating. The Jedi are not supposed to marry, or presumably have children. Not ESS, if you ask me. Anakin gets Natalie Portman; Luke spends two episodes with a perverse and distant crush on his sister Leia, leading only to one chaste kiss.
(Thanks, Bonnie!)
