Make no mistake, as emperor, Palpatine is a dictator--but a relatively benign one, like Pinochet. Its a dictatorship people can do business with. They collect taxes and patrol the skies. They try to stop organized crime (in the form of the smuggling rings run by the Hutts). The Empire has virtually no effect on the daily life of the average, law-abiding citizen. Also, unlike the divine-right Jedi, the Empire is a meritocracy. The Empire runs academies throughout the galaxy (Han Solo begins his career at an Imperial academy), and those who show promise are promoted, often rapidly. In "The Empire Strikes Back" Captain Piett is quickly promoted to admiral when his predecessor "falls down on the job."
