[Star Wars] Why would Luke — or any poor Tatooine teenager — hate the Empire?

Luke tells Ben he hates the Empire, even before they kill Owen and Beru. He already has friends in the Rebellion. He himself joins the Rebellion.

But why do they care? They aren't old enough to remember the Republic era. The Old Republic never ruled Tatooine in any case. It doesn't appear to have undergone a big change between trilogies.

Did the Empire make life on Tatooine worse for poor farmers? How? It was already a poor, dry world ruled by crime lords who made slavery legal.

Just because he's out in the middle of nowhere does not mean that he doesn't know about things happening in other parts of the galaxy. He knows that Biggs, his best friend, used the Empire as a way to gain piloting skills and then jumped ship to the Rebellion - which is exactly what Luke was planning on doing, had the droids not shown up and changed his life.
