I'll put it this way.
Quality of Life indexes are mostly BS.
Pretty much ANYTHING that tries to compare countries is BS... outside of things you can more or less count, like economical and military wise.
There are too many factors... not to mention it's all culturally different. Someone from Russia, the UK, Algeria and Brazil all have different ideas on what makes life "quality."
The list above seems pretty Caucasian-eurocentric-male biased.
I know france isn't the first place i'd choose to live if I was muslim or a woman.
Or Switzerland for that matter... what with their recent minaret ban... and universal woman's suffrage not quite coming across until... 1990 was it?
