The past is the future? Focus on the big picture
Format: Hardcover
This book isn’t just about economics; it also takes a captivating look at history. Written in a style similar to his previous book, "Big Debt Crises," Ray presents history in cycles. To make things easier to grasp, he added some helpful features: passages are bolded for a quick read, and a red dot marks principles that are considered timeless and universal truths.
I really appreciate the QUICK-READ option. It’s so easy to overlook key points in a long book, but the bolded sections help me focus. For example, one universal truth is, "Throughout time, the formula for success has been a system in which well-educated people operating civilly with each other, come up with innovations, receive funding through capital markets, and own the means by which their innovation..."
The book is divided into three parts: How the world works, How it has worked over the last 500 years, and the Future. The first part explores the rise and fall of empires. The second offers an in-depth look at the Dutch Empire, the British Empire, the United States, and China. The last part looks ahead at what’s to come. The appendix even includes a computer-generated power score for 11 world-leading countries.
I haven’t finished the entire book yet, but after reading some chapters, I can say Ray did a fantastic job condensing 500 years of history into an accessible, engaging format. The graphs also help clarify his points.
It answered many questions I had, like how pandemics have impacted the world. Instead of flipping through multiple books to find answers, I can find everything I need here.
What I also really appreciate is Ray’s honesty. He doesn’t shy away from tough issues. If he's not an expert on something, he clearly states where he learned it from. He’s straightforward, sincere, and speaks his mind.
Even if you do not believe that history will repeat itself, you will still enjoy reading this book.

Phenomenal book, one major criticism
Format: Kindle
Great book. Dalio does a remarkable job seeing the bigger picture and providing confidence through historical events/ever repeating cycles that you can predict at a high level what is coming next for a given country or the world and plan accordingly. The corkscrew of evolution analogy is a perfect one, where the human race has up and down cycles but always trends up longer term thanks to technological innovation.
My one criticism is he speaks out of both sides of his mouth in one instance, presumably because he doesn’t want to upset any high ranking politicians or leaders he may be friends with, which I found to be disappointing.
On the one hand, he notes at the start of the book that no two democracies have waged war with each other, wars have only been fought between dictators/police states and democracies or just dictators/police states.
Then later on when discussing China, he all but excuses and rationalizes their increasingly authoritarian state, as seen by Xi crowning himself leader until death and abolishing the precedent of 2 5 year term limits as of 2018. He blesses the Chinese approach of a few rulers knowing what’s best for all, as if those rulers are acting in the broader interest of Chinese people, and that’s an acceptable alternative to democratic rule. He cites the recent video game ban as having merit or at least being understandable, suggesting that he thinks the ends can justify the means. All the while there’s no mention of the atrocities of Mao under this authoritarian type of rule, no mention of the Muslim genocide going on now, the suppression of free speech and jailings and beating and murders of those that oppose the current regime, no mention of internet censorship, etc.
To bring the criticism full circle, he doesn’t link his first point on wars and authoritarians always being involved in them, with the fact that China is an authoritarian state and therefore it’s rise threatens the free world and human progress. Ironically, he does correctly acknowledge China’s opening up to market and establishment of capitalist principles for rocketing them toward the US in terms of power, while refuses to critique the political system despite its history of failings, violence and pain. Russia invading Ukraine couldn’t drive this point (ie the civil or political system being as important as the economic system to the long term success of a country and world peace) home any harder.

Can be effectively used as a working tool for the predictor (not just for investments)
Format: Hardcover
This is one of the best works on the declining economy and US, associated possible revolution/civil war and later major power war, that is presented in a clear, convincing and replicable way. Kudos to Dalio!! More importantly, the contents of the book can be used to predict upcoming events rather than just perceiving the world on fire with several likely upcoming breakouts (e.g., war with China over Taiwan, the likely loss of our reserve currency, the unsustainable and uncontrollable burgeoning national debt which grows by a trillion USD every 100 days). The author makes a valid case that significant events are moving very rapidly and, for the rest of the 2020s, things are going to get a whole lot worse for the non-elites in our society. Of note, the book was actually written in 2020, published the next year, which then allows the readership now in 2025 to verify the accuracy the observations and predictions. Right on target!

Great book for understanding how the world works!
Format: Hardcover, Format: Hardcover
Dalio has a unique perspective on the topic of the changing world order. He is a successful businessman who has spent his career analyzing economic trends and patterns, and this book is a culmination of his findings. His writing is clear and concise, making complex economic concepts easy to understand.
One of the best features of the book is its organization. The book is broken down into 14 chapters, each focusing on a different aspect of the changing world order. Dalio starts with the big picture, examining the major forces driving the changing world order, before delving into the specifics of each major empire, including the Dutch, British, American, Chinese, Soviet, and Japanese empires. Ultimately, he brings everything full circle by discussing the changing world order today and what the future may hold.
Another great aspect of the book is the way that Dalio weaves history and economics together. He doesn't just present economic theories in a vacuum; he uses real-world examples to show how they have played out over time. For example, in Chapter 5, he discusses the Great Depression and how it shaped the changing world order in the 1930s and 1940s. He also uses the rise of populism in Chapter 7 to illustrate how economic inequality can lead to political instability.
Overall, I would highly recommend "The Changing World Order" to any intelligent human interested in economics, history, or politics. This book is a must-read for anyone who wants to understand the forces shaping our world today and what the future may hold. As Dalio himself puts it, "understanding how the world works is essential if you want to accomplish your goals and live a fulfilling life."
Here are some key takeaways from the book:
The changing world order is driven by three major forces: the changing relative powers of countries, the changing relative productivity of countries, and the changing values of countries.
The rise and fall of empires is a natural part of the changing world order. Each empire has its own unique characteristics, but they all follow a similar pattern of rise, peak, and decline.
The post-World War II order was built on the idea of free trade and cooperation between nations. However, this order is now under threat due to rising nationalism and protectionism.
China is currently on the rise and is likely to become the world's dominant economic power in the coming decades. However, although this rise is not guaranteed, and there are many challenges that China will need to overcome, the US needs to step up its game on several fronts to compete.
The future of the world order is uncertain, but there are a few things we can say with some degree of certainty. For example, the rise of automation and artificial intelligence is a hot topic today likely to have a major impact on the global economy in the coming years.
Overall, "The Changing World Order" is a well-written and informative book that is sure to appeal to a wide range of readers. Whether you're a history buff, an economics nerd, or just someone who wants to better understand the world we live in, this book is well worth your time. As Dalio himself says, "The more you know, the more you'll understand, and the more you'll be able to make informed decisions about your own life." Five stars from me, give it a read!

10/10 Recommend
Format: Hardcover
I took Jeffrey Sachs's Globalization class on EDX Academy and somehow stumbled upon this book in between class and finding books around the subject.
I watched his youtube video that generalizes the book and was blown away by how my current class I was taking aligned with it.
This book is an easy read, and especially for those who aren't well-versed about world history and world economics. I will admit that I do love history, and am learning economics, so this book was a beautiful way merge all these timelines together.
The book breaks down and summarizes key points in world history and economics to make points to get the message across each chapter.
Font size is great! Might even be considered larger compared to other books.
The only thing I wish this book provided was thicker paper in the physical book itself, especially for the hardcover version.
If Ray Dahlio ever comes out with a special edition of this with a higher quality paper, I would gladly purchase it for my collection.
