There are authors who wrote about common sense things about ordinary injustices or follies of their time, which because of today's brand of insanity come to appear uniquely poignant and prophetic. But Orwell wasn't that, or wasn't mainly that. Orwell had lived through a hell of a lot of non-mundanity (British colonialism, Spain's civil war, Nazism and World War II, Stalinism) whose injustices he wrote about. It's not like he just wrote about 1940's common places against ordinary injustices.
