I don't buy your second point here, because while in reality yes, the rich have the ability if not necessarily the inclination to deal with the world's problems, stories about those problems tend to maximise emotional impact by making their protagonists part of whatever strata of society is most affected by them. In the story of english democracy, the Chartists are much more sympathetic than Disraeli, and Christy Moore is unlikely to write a song praising John Major for his role in the peace process.
If Eliezer were writing an original story with a similar plot to MoR, he'd be well advised to amp up the prejudice against Muggle Borns and make his hero one. I suspect the narrow class focus here is an incidental result of the intersection of his interests and Rowling's, particularly her fondness for "salt of the earth" working class stereotypes. That is, Rowling made all the smart kids posh and Eliezer picked all the smart kids.
- This thread has run its course. You will find newer threads in the discussion section.
Another discussion thread - the fourth - has reached the (arbitrary?) 500 comments threshold, so it's time for a new thread for Eliezer Yudkowsky's widely-praised Harry Potter fanfic.
Most of the paratext and fan-made resources are listed on Mr. LessWrong's author page. There is also AdeleneDawner's collection of most of the previously-published Author's Notes.
Older threads: one, two, three, four. By tag.
Newer threads are in the Discussion section, starting from Part 6.
Spoiler policy as suggested by Unnamed and approved by Eliezer, me, and at least three other upmodders:
It would also be quite sensible and welcome to continue the practice of declaring at the top of your post which chapters you are about to discuss, especially for newly-published ones, so that people who haven't yet seen them can stop reading in time.
