Which countries have the best, and worst, living standards?

There's so much variance in the large countries this isn't that useful. How can you give one rating to a nation that contains Connecticut and Mississippi?

Honestly, these studies don't make any sense. Australia in the top 10? Sure, if you already own a house, but if you're renting there's no way your quality of life would be better than say a mechanic owning 3 acres with a 3000sq foot house outside of Ohio.

US 17th ... ugh.
