I agree. I've been always sensing that there is a strong genetic component how countries are governed, how people behave or how orderly institutions and businesses function in different countries.
I have an observation about collectivism. It looks like it has a duel or split personality. Collectivism of southern countries is strong on personal level. People bond strongly, let's say very emotionally with people that they know, like family, villages, work places/ workers unions. They also have strong national identity, but it stops at identity. They mistrust governments, they don't want to pay taxes, and underground economy is rampant. On this level they strongly divide big social construct, like country or big business, between they and we. "We don't want to share with them, they always cheat and use us". But when family and friends come for a visit southern hospitality is unsurpassed.
North Europe is different in this regard. People are more willing to pay taxes, people care more about common property, people are more willing to share wealth with all national we. North collectivism goes easily international giving to the whole world. On other hand, when guest and family come for a visit, you better bring your own food, lol.
There was a great example of collectivism in Germany during this recession. When most businesses in the world were rushing to cut jobs, Germany's businesses, instead of letting unfortunate people go, decided to keep all workforce and cut everybody's working hours and salaries. That's collective sacrifice at it's best, and there wasn't much resistance from the work force to do so. It's all we, it was all for us.
So, who is more collective, south or north? I guess we need to create sub groups for collectivism.
