I just want to add a small personal comment, being a Danish woman, living permanently in Africa.
I think that our opinions about the physical conditions in our lives has a strong relation to habits: what we are used to is easy for us to relate to and understand, and we tend to like it better, since we are inside our comfort zone, unless of course we are thrown in the dungeons.
So many aspects of sharing and cooperation comes easy for me having been born in and growing up in Denmark with its all-embracing social values including free health, free education, well-functioning public transport, and many more socially supportive elements. I take such things for granted as the foundation for a good quality of life, and I find it fair that wealth does not determine well-being.
Having lived for many years in Africa, I am aware that what I find "normal" is not available here. People have learned to live without a supportive public structure inside a reality where individual struggle for well-being is the daily activity. I often feel sad when I in my daily life experience that people suffer and die because they do not have sufficient funds to get healthy food or proper medical support, and that they do not prosper and develop their intellect because they cannot afford formal education or training. However, I also observe that many find this way of life normal. Most do not protest or demand changes, exactly because they are used to this reality and having not tried an alternative they cannot compare with something else. After all, we only know about day light because we experience darkness of the night.
Being able to compare, I have come to conclude that although a solid physical foundation in life does not necessarily mean that one becomes a better human being, it does mean that one can focus on other issues than merely survival. It is unfair that higher pursuits are only available for the wealthy ones - they anyway earned their wealth by taking more than their rightful share of our common resources - it must be something to which we all have access.
Conclusively, when we get the privilege to compare more realities, we are better able to put our habitual way of life in perspective, to compare, and then conclude and demand what we find being socially optimal for humanity. I am not supportive of any global political ideologies, all of which I find not useful in supporting society and nature. Instead, I fully embrace the values of cooperation, sharing, justice and allowing for a quality of life for all living beings in society and nature. I trust I received the seeds of these civilized values from being born a Dane.
