This book is not going to give you solutions to your functional stupidity. They show you all the ways in which we actively participate in the stupidity and then they're asking you to think and reflect upon it. Sometimes the stupidity is necessary, but often, it is not. It's up to you to decide in your own unique situation what is appropriate.
I loved it because I'm self proclaimed cynic/realist and I was still buying into stupidity. This book really caused me to think hard about so many things that I celebrate and do and it was a somber experience. But I don't mind it when a book cuts me down a peg or two. Often the best criticism is deep self reflection.
But that's just like, my opinion.
