I don't think fiction can be shrunk down, but I think lots of non-fiction books can.
I'm thinking specifically of some books that I've read in the past couple of years that include:
* Deep Work
* Influence
* Thinking Fast and Slow
* Predictably Irrational
* Getting Things Done
* How to Win Friends and Influence People
I think all of these books suffer from the common pattern of present an idea then a bunch of examples that demonstrate the idea. I don't think you lose anything by ditching the examples. The core ideas are usually well stated and don't need clarification or demonstration.
