I recently read some something that had the following premise: Immigrants leave their family and friends behind. People who are more empathetic have a harder time doing this. Therefore, countries with net emigration will grow more empathetic. Countries with net immigration will grow less. While just anecdotal, this is something that I've confirmed with my experiences. I'll add in that countries which were founded on a genocide that happened not too long ago, probably will have echos of this continuing for a long time. Backwaters also tend to be less aggressively restrictive of freedom, as greedy, aggressive people naturally navigate out of them.
