I had a discussion with a Star Wars nerd about this.
His view on Star Wars is that the Clones run the Empire.
And while it's a small point, the Empire's manners and decorum speak well of it. When Darth Vader is forced to employ bounty hunters to track down Han Solo, he refuses to address them by name. Even Boba Fett, the greatest of all trackers, is referred to icily as "bounty hunter." And yet Fett understands the protocol. When he captures Solo, he calls him "Captain Solo." (Whether this is in deference to Han's former rank in the Imperial starfleet, or simply because Han owns and pilots his own ship, we don't know. I suspect it's the former.)
He thinks that Vader treats Fett like this not because he is a clone (the last clone?) but because he has free will where Vader is nothing more than a puppet for Palpatine, and Vader can't stand that.
