Perhaps the biggest and central message of the Harry Potter series is the power of the individual over the collective. In this way, the series is a modern day recreation of the Fountainhead only told in the genre of childhood fiction. The story is largely about the the willingness of a traditional family group and an extraordinary white male to give their lives for an ordinary child. Because of the heroic efforts, a child without any extraordinary abilities can overcome the entirety of the government, main stream media, and the most powerful dark wizards of all time by having an unwavering faith in the goodness of himself, his friends, and his hero.

The heroes of the series at one point have to disguise their true selves using the Project Veritaserum (Polyjuice) potion order to infiltrate the central government's halls of power only to be horrified that it is being used to disseminate information about "undesirables (deplorables)" to the general public, create new teaching materials to be distributed to Hogwarts in order to indoctrinate children, and the corrupt government is so far removed from the populace that they have built monuments displaying the government's power over the helpless. The entirety of the set of books is a widespread display of the worst aspects of communist/socialist ideologies and their applications in government; and the ability of individuals to successfully defeat these ideologies through faith and determination.
