You are still trying to suggest that it immigration from other countries that has caused the social ills of the United States of America.
This is nonsense. The social ills of the United States of America are rooted in egotism and exceptionalism. From their founding they emphasized “Property rights” as sacrosanct and then coupled that with the rights of the Indvidual over the well being of the community and of collective rights.
When they spouted words like “Freedom and liberty” it meant “The freedom and liberty to do AS I PLEASE without the society censuring me”. It was an appeal to egotism that was both selfish and childish,
The concepts of Community and of the Social well being of a society which led to the pursuit of Socialism and Communism in other countries was denigrated and ridiculed to the point where they are seen as evil. What was promoted was the “I” and feeding ones own ego no matter the cost and free of all responsibility for the same.
Those promoting this ideology tended to be very wealthy wherein they could count on that wealth to provide what the society and collective once provided. It was very much “I do not NEED any of you I got my money” mentality. This mentality carried over to the environment itself with the premise that if Mother Earth could no longer provide clean water and food in abundance then that same money would.
This inevitably led to Corporations as people with them claiming the right in Courts to do as they please with what they consider “their property” and to pursue profits at any cost in service to the “I” even if it at the collective cost of everyone else in society.
The reason Iceland does well is not because they are all white. They do well because they maintain and promote the concepts of community and of collective well being.
