I have come across the
World Values Survey that tries to answer the question in an empirical way. Based on survey launched every five years, they organise countries in a 2-dimensional matrix:
This is the resulting map for 1999-2004:
Some of their placements run counter intuition (compare e.g. Austria's position vis-à-vis Great Britain and Germany). I also tend to think that the survival / self-expression scale may rather capture a country's current situation than underlying cultural values, as changes by half a point or more from one cycle to the next are quite common. [
Questions here include neighbourhood security & pollution, environmental taxation, "maintaining order" vs. "free speech", confidence in the police, the parliament, and government, etc.). Moreover, I don't think that "party membership" is an adequate measurement to conclude on survival / self-expression values when comparing between the US, Western Europe, post-communist countries and China. The fact that more than a third of respondents in Germany and Japan never use a computer raises some doubts on representativeness.
Nevertheless, here is their latest 2005-2008 map (next update will come in 2014):
So, what is their result on which countries were most different from America in 2008 (sum of absolute differences on both scales)?
1. Taiwan (4.91)
2. Hong Kong (4.75)
3. Bulgaria (4.71)
4. Japan (4.58)
5. South Korea (4.56)
In 2004, the Top 5 were Russia, Bulgaria, Ukraine, Estonia and Moldova.
Oh, and the closest one in both 2008 and 2004 - surprise, surprise: Canada.
