I have good news and bad news. The world doesn't stand still. There are some iterations that destroy the structure of society, after which a new structure must be built. The oligarchies of today will meet their end at some point. And, no amount of preemptive effort can prevent that. That's as the good news go, in as much as they are good news.
These are not my ideas exclusively. If you want to hear them from people that has dedicated a fair amount of time at exploring this subject and gathering data, I recommend these books:
- Capital in the Twenty-First Century, for an overview of historical change. You will find that the author agrees with you in many accounts.
- The Collapse of Complex Societies, by Josph A. Tainter.
- Principles for dealing with the changing world order.
The bad news is that the most likely iteration coming around the corner is human's lost of control of our societies in favor of machine intelligence. It's not going to be as "peaceful" as the rise of the post WWII world order, but I hope that we survive.
