What I said this is complex. Cultural patterns are difficult to influence.
In my previous posting I wanted to start with slavery, but then it's easy for some to say, yeah blame it on the slavery.
In the Netherlands this is known as the Caribe pattern, because people of the Surinam and the Antilles have the same. This also linked with the 'plantages' the slavery. I remember one of my fist colleagues, she came from Surinam and told me her family background in here case a mix of Chinese, Creool and Jewish plant owners and all what happened in the old days....
Partly this phenomenon is also connected with this work of Christopher Lasch:
https://en.wikipedia.org/wiki/The_Culture_of_Narcissism
Because it's since the sixties also quite common in 'the Western world'.
I'm not explicit in this matter, I see advantages of communitarism; so strong ties, sense of belonging etc. I also see the shadows of strong ties, closed communities etc, people must be able to make their own lives. People lived in the past kind of pre-programmatic lives, that's gone, and that has partly positive sites (I mean NYC this is very well known I guess and 'New' or 'Old' Amsterdam doesn't make the difference in this respect).So I'm kind of middle of the road.
And IMO in this matter it's practice what you preach. I have been divorced, new relationship, composed family life....so I'm the last one to give some preaches about this ;)
