Star Wars makes perfect sense at one level of course. We humans like to see the hero being oppressed then winning, it's one of the basic mythologies of our species. However, it also has to be said that the Star Wars universe doesn't make any economic sense:
Yet the existence of slavery in the Star Wars universe is itself something of a mystery. Yes, economic historians have come around to the view that Southern slavery in the U.S. very likely was profitable, whether or not it was sustainable. But in a technologically advanced galaxy, exactly why human slave labor should be more profitable than droid labor is not entirely clear. One would think that robot miners, for instance, would work more efficiently than humans, and with considerably less attrition. But in the Star Wars universe, mining is done by human slaves.
As Adam Smith himself was pointing out paid labour is more productive than slave at anything above the most basic human grunt work. Something that just doesn't have to be done by human or animal muscle power in a society with any form of technological advancement at all. Even today's protested versions of slavery aren't that straight chattel form and even then, again, they're restricted to the most basic of tasks.
The thing being that for all its vileness slavery just isn't economic given any modicum of technology.
But the fictional universe still doesn't make sense even after that. In the same way that Red Mars from Kim Stanley Robinson doesn't. They both have people poorer than today's - agreed, rich world - society in a more technologically advanced scenario. This isn't one of the possible outcomes.
Assume that the machines are doing very much more - that's what technological advancement means. There will be more for all to consume therefore - no one can be poorer.
Or perhaps we then posit that only some gain the production of the machines. Analagous to the current complaints that the capitalists will get all the output of the robots and the rest of us will be wandering bereft and jobless. Thus the rich get richer and the poor get poorer. This isn't, as we say, a possible outcome.
For think what happens. The machines do much but we out here don't get any of that. So, what will we be doing? We'll be doing exactly what we are now of course. Producing things that other humans consume, consuming what other humans produce. Sure, those consuming the production of the machines will be very much better off than we are but we cannot be poorer than we are today. Simply because we can produce and consume what we do now without that next generation of machines and therefore we will.
There is no manner in which a more technologically advanced civilisation can leave some portion of us worse off than we are now. Yes, OK, it doesn't matter as a background to a myth in which the hero triumphs but it does when we consider what we need to do about our own futures. Even at the worst the robots cannot make us worse off.
