oh bother, here's the original article: "epic pooh" (1978) https://warwick.ac.uk/fac/arts/english/currentstudents/under...

I don't know how closely Moorcock read his rabbits: in the Watership Down I read, Le Guin's Omelas existed as a warren, a little more realistic and a little less difficult to map to our own circumstances, and Adams had the honesty to explore the ambiguity, the decency to point out the economic and cultural benefits that Cowslip et.al. got from their arrangement.

Milne, on the other hand, doesn't ever delve into the explicit delapinisation of the less fortunate.
