That sounds a lot like Norway though, didn't they have this massive amount of money from some natural resource (oil I think) and made a big pension fund for the population?

There are obviously also counter-examples, but a currently-democratic country finding a new way to make money from natural resources, I wouldn't expect we have a large enough sample size to really say anything about that with certainty.

Edit: The Norway thing being (for those interested):

> [The oil fund] was established in 1990 to invest the surplus revenues of the Norwegian petroleum sector. It has over US$1.3 trillion in assets, including 1.4% of global stocks and shares, making it the world’s largest sovereign wealth fund. In May 2021, it was worth about $248,000 per Norwegian citizen.

Because oil was discovered in modern times when Norway was already a developed society with strong institutions and an educated populace.

In contrast, El Salvador right now is still fighting barbarism and anarchy.
