George Orwell died in 1950, 1984 was published in 1949, Animal Farm in 1945 and post-war Britain was moving leftwards towards a Social Democratic state. So the sort of argument nowadays used by conservatives against Socialism (something which arose in the 1970s-80s) probably wouldn't have being even heard by him within in the single year before he died.

This question piqued my curiosity, so I looked up what he had to say about the reception of Nineteen Eighty-Four. Here's a blog post with a few excerpts from his collected works. Among them:

My novel Nineteen Eighty-Four is not intended as an attack on socialism, or on the British Labor party, but as a show-up of the perversions to which a centralized economy is liable, and which have already been partly realized in Communism and fascism.
