As we see in the graph presented in the video, 50 countries experienced GDP growth of at least 3 percent because of the new Bretton woods system. Even countries in Africa and Central America that might not have been the most technologically developed, were benefitting. After the system was disbanded, only 9 of those countries continued experiencing growth.

As Wertz says in the video, this is because many countries reached peak industrialization and decided to focus on the exporting of raw materials rather than continue developments.
