Harry's single ambition through the books is becoming a member of the Wizarding police/SWAT team (Aurors), totally integrated into the system. The only things he had any personal problem with was occasionally who's in charge. In fact, he stays (almost) moot through the entire series of books on questions such as the fact of elves being literal slaves, where people who speak out (e.g. Hermione) are portrayed as shrill whiners.
