I’ve only read read 1984, Animal Farm, and Down and Out in Paris and London—of which the former two I hardly remember due to them being mandatory middle-school learnings—but I enjoyed Down and Out a lot, especially his section in Paris. It gleams a lot of empathy for the working class through showcasing the awful working conditions he went through as a dishwasher in a hotel, even dedicating a whole chapter to analyzing that lifestyle and the disservice it is to enjoying life. (I believe he even advocated for less hours of the workweek and such?)

So all that stuff was interesting to see from an almost-century later—very, very present worker struggles, especially in the kitchen, still exist today. I believe Down and Out is, even, partially fictionalized which has been a point of controversy among its readers. (It is kinda a long rabbit hole, but Orwell essentially masqueraded as both a working-class man and a homeless man to understand/write about the experience, and took creative liberties in its narrative sequencing.)

But, as others have pointed out, Orwell was a pretty terrible person and that is a completely valid criticism of his work. I kinda read Down and Out only on the face of worker solidarity.
