Your list is a list of countries that also happen to be at the top of this one [1]. They are the countries with the most freedom and capitalism. People are generally happy when they're free to own property and become prosperous.
I think you are confusing social democracy and communism[1]. I agree with you that people should be free to own property and become wealthy. However, I do not think it should come at the cost of removing social net for the less lucky.
