I guess I only just realised that Star Wars is very specifically an American mythology in almost exactly the same way that Lord of the Rings is an English mythology.
LOTR: deeply pessimistic and quietly a bit racist story about the old upper class losing their empire, right around the time England was losing its.
SW: a 'greatest hits' of USA pop self-image released right at the Bicentenary: War of Independence, Wild West, WW2, space, computers. Brash farmboy accidentally saves world.
