So because he had a mom and was good at building stuff, that negates him being a slave and having a shitty life? Luke's aunt and uncle were loving, he didn't seem to have too shabby of a life. And you cant say "start from AOTC," those years he spent as a slave were the years that mold you into the person you are.
So in the end, Anakin's life starts in TPM and is far from ideal...
So what did we see about Anakin's slave life that was so terrible. We see him doing what he loves most: building things, we see him having a loving mother, he has friends to play with and he is making his very own pod racer in the backyard.... Honestly, Anakin's slave life didn't look too terrible to me.
we see about 30 minutes of his slave life from PG perspective. There were slaves in the old days that got to live in the house and cook and clean...they had other slaves or "friends" to talk to...are to take that they didn't have it so bad compared to the ones that were free? Come on man, you know better than that. He was so well treated that he had a tracking device implanted in him that would blow him up if he left...he really had a GREAT childhood.
And Luke had it real bad...not being allowed to go to Toshi Station to get some power converters when he had...*gasp*...chores to do. Painful.
So he has a tracking device. I didn't see Anakin SUFFER very much. Luke neither, I agree, but he clearly disliked his life on Tatooine. I didn't see Anakin disliking his life very much, I didn't SEE hardship... What was the point of slavery there? So we add our own knowledgde of slavery and imagine how that much have been for Anakin? I saw no hard labour, no whipping, no slave ships etc...
Less than Luke? They pretty much did the same thing. Luke flew his T-16, Anakin a podracer. Luke had to fix condensors, Anakin anything that came round at Watto's, Luke had a grumpy uncle, Anakin a grumpy owner, Luke had a sweet aunt, Anakin had a sweet mother, Luke couldn't go to follow his dream, Anakin could.
Luke did follow his dream, and got more out of it, he could have gone whever he wanted if he didn't care for his parents, Anakin on the other hand had a tracking thing in him (I believe).
Anakin was only able to because QGJ was able to persuade Watto to put him up for a bet, if Watto said no...Star Wars would be very boring.
