Well guys, I cannot lie to you. I gotta say that was probably my favorite urban planning book I've read this year*, it was such a banger from cover to cover.
The main idea here is promoting Asset-Based Community Development, which mostly means looking at communities primarily by what they already have (mostly manifested in individuals and associations) rather than what they're lacking. By building up what already exists, other problems can get solved in a kind of non-linear fashion.
I think what I liked so much about this book is that I've been building up the ideas in this book on my own for a while (mostly that modern approaches to urban planning/community development don't really work as well as we'd like them to, and we need new tools and philosophies to approach creating real places with swag and soul) and this book just hit the nail on the head for describing what I was already kind of on the path to figuring out. Namely, consumer societies don't give true happiness; collective projects are what bring communities together; localism is the real way; we cannot systematize what really matters; what really matters are the finer things in life, what money can't buy. There's a hundred little nuggets in here that build up to the core thesis of the book, that being that the world has had enough of the bullshit in consumption-based healing and needs a more dedicated, constructive approach.
The book spends it's pretty brief page count focusing less on specific case studies and more on the building blocks of why this works and the core logic of the approach. Some people might care more to see examples, but I think resources are provided at the end for that purpose.
It ends on a real plot twist though (and I will now spoil it): the recipe for success outlined here is high impact, transformative, empowering, and does not require federal grant money, feasibility studies, or management consultants. The key to success literally requires yourself, a clipboard, and sheer tyranny of will. It's wild but you gotta read the book to find out more.
I read this alongside two of McKnight's other books (The Careless Society and An Other Kingdom) and I recommend you do as well if you want to get into this. It requires a real shift in perspective and the willingness to get off the beaten path, but if you have a real love of the game and are motivated primarily just by helping people, this one's for you.
Also, the real, real plot twist is in the last few lines of the book. You can figure it out as the book goes along, but to spoil it: this book is actually a long, pragmatic argument for the power of love and friendship. And that's what's up.
*It's my second favorite overall. This book got bodied by Why Greatness Cannot Be Planned
