I don't mean to be flippant, but what you have described sounds an awful lot like the economy. In the book Sapiens, the author describes organisations, money, Capitalism, Communism and more as religions without a deity. The detail that you included which stopped me from calling this utopian is "form of a hierarchical network". It is of course important to recognise that a classless society is impossible. As for solving racism, I think I'm less optimistic. I mean, I don't think people today can even agree on what "racism" as a term actually means.
