I don't mean that non spanish authors are worse (I dislike many of them because they were forced to me too early, when I preferred Dahl or Tolkien), I am just saying that it makes no sense to recommend Shakespeare instead of Cervantes in Spanish Literature class, where they recommend/require books. I can't imagine Russian Literature teachers requiring "Episodios Nacionales" authored by Galdós, a book about spanish history/politics in the XIX century over any russian author about any russian theme.
