No, the title is 'Is Facebook Making Us Lonley'. No nation is compared to another

[Bluenorthwest]

and nothing in the article concludes that Americans are the most isolated and lonely, the article has nothing to do with international comparisons. At all. That's your take on it.
What do you think about the suicide rates in countries you insist have close friends and families, which you also claim Americans do not have? Does Japan have a suicide rate double our own because they are so much less lonely, do your think? I sure don't.
There is nothing in the article that makes the conclusions you made into the title of the piece, it is simply not in the article.
Loneliness is a human condition, not a national trait.
