I recently met someone from El Salvador. We didn't talk about Bitcoin but she said that peoples idea of "making it" isn't to start a business, become a doctor or being a music/movie star - their idea of "making it" is leaving the country.

I bet that's related. Especially the well off young people have cognitive dissonance with the idea of perspective inside the country. Bitcoin in El Salvador means staying in the country - and that's fundamentally opposed to their previous goals and dreams.
