I resented being constantly 'corrected' on the local accent I was picking up from school as a child, but now I appreciate that an RP or close to RP accent turns down the difficulty slider in certain British interactions.
In general, the fact that Orwell is remembered in the public consciousness as the 1984 guy is a shame (and is particularly jarring when right wing populists invoke his name to decry people who try and get them to stop lying).
Orwell's essay 'England Your England' (the first part of 'The Lion and the Unicorn') is perhaps his piece which is dearest to my heart, as a patriotic but anti-reactionary Englishman. However, of broader appeal are 'Shooting an Elephant' and 'A Hanging' - essays which expose the brutal workings of colonialism better than any jargon-laden journal of post-colonial theory ever could.
But that's just the start when it comes to Orwell. I don't think the man wrote anything not worth reading and at his best he was near-untouchable in his ability to capture in the written word a society and its injustices.
Orwell pointed this out in England your England which was written during the Blitz. Many of the problems he described have only got worse in the decades since he wrote about them in my opinion. While the essay is a bit dated now (it predates the post-war era of globalisation for example which created new axes in UK politics) I still think it's essential background reading for people who want to know what's wrong with the UK, and it's an excellent example of political writing in general.
