"What Qui-Gon had to offer at the moment was worth as much as cost of a slave." What if someone returned to Tatooine and offered Watto enough to recoup his losses from betting on the race...or MORE? "And if Anakin wasn't worried about it, why would Padme? If Anakin had approached her in the meantime, telling her that he need to get enough money to free Shmi, she would have probably done whatever she could. But he didn't." It sounds like you're supporting my opinion that Anakin should have insisted that someone go back and free Shmi to give her a chance for a better life. Anakin's attitude should have been... "Thanks for everything you've ever done for me. You've been a great mom. I'm off to start a new life and fullfill my dreams and once you're free, you can start a new life too." instead of... "I'm off to fullfill my dreams, but I don't want to impose on any of these adults around me by suggesting that someone go back and pay off Watto so Mom can be free." As I see it, Shmi's problem could be easily solved... ...but Lucas wants to leave her there.
