Empirical Evidence?

Hello everyone, again...

I have posted something else recently, I apologize for my intensity, but I try not to post unless I have serious doubts about something.

I'm trying to find real case studies, like Selco's in the Balkans, where an individual shares their realistic wisdom about what they experienced, what was useful or not, and what things they didn't waste their time on. I would like to find things like this about Argentina or Venezuela or Cuba. Contexts in which everything has gone to hell, but not because of a war against an external enemy or similar, but because of the government's own incompetence.

Greetings and thanks.
