Padme Amidala was queen, and then a senator for one of the more prosperous planets in the civilized galaxy. She could have easily bought and sold Anakin's mom 20 times without the royal treasury so much as blinking!
But for 8-10 years or whatever, she left the mother of the kid/jedi/manchild she loved to rot on the arse-end of the galaxy. She couldn't have spared three days to run over, buy her (for cheap too), and bring her back to the palace? She could even have sent a servant or something and a shuttle to do it!
"Happy birthday, Ani! Here's your mum!" Joy all around, no dark side, no Darth Vader.
No Emperor Palpatine, no Empire, no Rebellion(s). The Vong? Waxed before they could so much as say "Resistance is futile."
But noooooooooooo, trillions of people dead, worlds burned to glass, etc. etc. all because one little girl was too busy to rescue somebody's beloved mother from life/death on the place furthest from the bright spot in the universe.
