I think you could easily substitute “High Trust Society” for “Self Expression Values.” These countries accomplished something very special. That’s why they taught modern civilization to the rest of the world and not vice versa.
Interesting that in Protestant Europe the extended family was weak to the point that society became your family. The pre-schism church’s ban on cousin marriage may have helped. These are the societies which have among the highest wealth redistribution. They are now struggling with immigration. Money transfers to your family is one thing, to foreigners is another.
I’m beginning to see leftists not as stupid (not entirely, anyway), but as having a more primitive morality. Within the family, opportunities are considered and guarded as property. It is not trivial to adopt the capitalist ethic, where we allow competition for opportunities, while respecting physical property.
