I hate to bust on your favorite comment, but I will point out that Luke was re-joining his childhood friends in the rebellion, re-connecting to his father's Jedi legacy, and the hero's journey business was not even suggested by Lucas until years after the first three films were in the can. Luke does join arms with an all-alien rebelling force on Endor in the third film, and it's race and religious exploitation, not white guilt.

Anyway, if you want to do something that helps people, do it because it helps people. If you get something out of it as well, that helps you sustain it and help more people for a longer time.
