Orwell was an cynical observer, not an organizer. Orwell on socialists, from "The Road to Wigand Pier":
"In addition to this there is the horrible–the really disquieting–prevalence of cranks wherever Socialists are gathered together. One sometimes gets the impression that the mere words ’Socialism’ and ’Communism’ draw towards them with magnetic force every fruit-juice drinker, nudist, sandal-wearer, sex-maniac, Quaker, ’Nature Cure’ quack, pacifist, and feminist in England."
That book is about why socialism in England never got much traction. Yes, in the late 1940s and 1950s, the UK had "lemon socialism" - the government ended up owning the steel, coal, and railroad industries, all of which were in trouble. That was not a people's movement.
For the organizer's point of view, see Saul Alinsky's "Rules for Radicals".[1] Alinsky is all about how to organize and win, working from the bottom. Alinsky was a labor organizer. His approach is independent of political position.
Orwell offers cautionary views, but he's too cynical to propose solutions.
