I think that culture diversity is a part of the Earth's life, not of my life. I simply accept it, nevertheless struggling to answer my own personal questions about life in general, and about my life in a special form. I also agree to what Mr. Tumpliner said in very clear words. Still I understood the subject of your question, but not its meaning.

My understanding of the human dilemma contributed most to my conscious awareness of "diversity".

Every one supposes unique temperament, I think , so I believe if a person can have more opportunities to choose the living way , he would be more flexible to live . You cannot frame a horde of people into one moral , one culture or even on people and hope they are all happy . In modern society , people are likely to move to other countries with other cultures . Like umpliner said , if you can more options , you can shift to the Living model you like . Probably , you would be happier than living in a single , monotonous culture .

I think a country with a strong national culture is better off than a country with a "mixing pot" of cultures, like in the USA. That is because cultural pressure can be more easily applied to the individual who is not living up to the standards expected, or in violation of some aspect of the culture. If the individual in the USA receives more pressure from a sub-culture than he wants to feel he can just opt out of that sub-culture and join another sub-culture. So, cultural diversity is good if the individuals stick with their original culture, and are not forced to accept a "mixed pot" culture, that is usually weaker, in place of it.
