Why did we never see Ewok slave labour camps in ROTJ? As far as we knew from the film alone, the Empire never really bothered them (in fact, one could go so far as to say they coexisted peacefully because I assume the Empire knew about them and deemed them not a threat), possibly even had good relations with them.

They should have thrown in some forest-clearing scenes or something where AT-AT's step on Ewok orphanages or stormtroopers dump toxic waste into Ewok wells or something so we could actually feel like they were being wronged in some way. As far as we know, the Rebels just showed up and took advantage of them by using the poor little bastards as meatshields to attack a far-superior Imperial ground force to lessen the casualties of the Rebel saboteurs.
