The Smurf Village as a Marxist Utopia:
The Smurf Village itself is a perfect model of a socialist commune or collective. It is self-reliant, and the land is not owned by individuals, but by the entire collective of all the Smurfs, if the word 'owned' is even appropriate.
Papa Smurf represents Karl Marx. He is not so much the leader of the Smurfs as an equal revered by the others for his age and wisdom. He has a beard, as did Marx, and thus could conceivably be a caricature as well. And lastly, he wears red, which is the traditional colour of socialism. Brainy Smurf could represent Trotsky. He is the only one in the village who comes close to matching Papa's intellect - he is a thinker. With his round spectacles, he could also be a caricature of Trotsky. He is often isolated, ridiculed or even ejected from the commune of the village for his ideas. And of course, Trotsky was banished from the USSR.
Despite their different professions/distinctions, the Smurfs are all completely equal. Thus, while the occupations of certain Smurfs, such as Farmer, Handy and Greedy, are more important than others, such as Clumsy, Grouchy, or Lazy, there is no feeling that certain Smurfs are superior or inferior to others because of their work, or level of skill, because ultimately, everyone is a Smurf first.
