Fahrenheit 451 - Ray Bradbury

Of all the classic dystopian books, I like this one best.  Bradbury combines the underlying authoritarianism with the bread and circuses use of technology into something that is clearly related to what we live today in the West.  He also incorporates the idea of alienation - alienation from others, alienation from the self.  Isolation and medicated depression in the midst of a society of happiness.  His characters also have a bit more substance, a bit more humanity than the other two books.
At the heart of the books society is an issue that is very much topical right now - the issue of identity and living with diversity.  The book's solution is mindless self-replicating mass identity.  (Similar idea behind the Homelands concept in "Adjustment Day".

1984 - George Orwell

1984 was a better read than Brave New World for me.  It comes a little closer to the rough authoritarianism that is on the rise in many places right now.  You can still see how Orwell was affected by his profound disillusionment with Stalinist Russia. 
It is interesting to compare the role of sex in those two books; in Brave New World it is a form of social distraction, part of the bread and circuses machine.  In 1984, it is used as a form of social revolt.
This dystopian vision probably captures the experience of the poorest elements f the west, particularly in the U.S. - the grime, the poverty, the hostile authoritarian oversight.

Capital - Rana Dasgupta

A look at the rapacious capitalism of Delhi, and the dysfunctional, inhumane society it has created.  A look at capitalism and private sector services and where they end up without government regulation with a corrupt power elite.  You can see how government and private capital work hand in hand to disenfranchise and exploit citizens for their endless greed and profit.  Book is well-structured into specific sectors - property, health care, infrastructure etc. 
Built around research and interviews with people involved in the various sectors examined. 
Kind of an examination of the pure capitalist model carried to an extreme.

Lot in there.  Worth rereading.

Men Without Women - Haruki Murakami

A collection of short stories, each one in its own way, about men without women.  Some very original approaches to the them.  One of his easier, more enjoyable books to read.  Perhaps the short story form makes him cut through some of the thick accumulation of detail that you find in his novels.

Worth a reread at some point.

Brave New World - Aldous Huxley

Reread this old classic.  I find his style a bit hard to wade through - always a tendency towards a didactic or ideological tone.  Social control instruments - sex and drugs.  Prescient in its own way when you look particularly at the U.S. and, to a lesser degree, Europe.  I would say this book is partly the result of Huxley's encounter with American culture, particularly in California and Hollywood once he moved there. (But then, dystopias are usually more about their own time than any future time...)
His view is more valid for the years preceding 2000/2010.  Right now I would say the emerging world situation is closer to the dystopias of Animal Farm, 1984 and Fahrenheit 451 - more about fear as direct social control, less about bread and circuses as social palliation. 

Kids These Days: Human Capital and the Making of Millennials - Malcolm Harris

A brilliant analysis by a Millennial of the economic and social forces at work over the past twenty years or so that created the environment which has shaped his generation's culture and outlook.
A very pointed examination of the role of corporate culture, economic individualism, and the every-man-for-himself  ethos of the ruling oligarchy of the U.S. in shaping the stressful, isolated and alienated space we now occupy.
The book is well-divided into sections on various important shaping influences, starting with the mania around homework, moving through university, changes in the work environment, decline of social support networks, identity politics, pills and so on.

Not a hopeful book.  At best 50/50 - he sees either fascism or rejection/revolution as the two alternate paths...

Worth rereading as there is a lot to absorb.

Adjustment Day - Chuck Palahniuk

This book has created quite a bit of controversy with its suggestion in the course of the story that racial groups in the U.S. should inhabit different homelands.  And in fact, the first half of the book reads like a serious, reasonable proposition put forth by a group of essentially white suprematists. 
You have to continue to the last half of the book, however, once the whites, blacks, gays and latinos have all been resettled (or shipped out in the case of the latinos).  As the distinct homelands establish themselves and develop, Palahniuk begins to bring out the essential absurdities of all the current identity politics and doctrines.  Every community becomes a ridiculous and pathetic parody of itself.  In the end, we are left with a small group of fugitives from the various homelands who want to start again in a world where they are not defined by their narrow group identity.
Great sarcasm and parody, but somehow the writing in the last part didn't hold my attention well.

Still worth a read.
