It's corrected for cost of living, but when you look at the source for that data (http://www.numbeo.com/cost-of-living/rankings_by_country.jsp http://www.numbeo.com/cost-of-living/rankings_by_country.jsp), you may notice that many of the countries that have a very high cost of living are also the ones known for a very high quality of living. Some countries give back considerable more in exchange for those costs. In places like the UK you should really distinguish between London and the rest of the UK. Or SV and the rest of the US. Also, more than half of the countries listed are inside the EU, which for developers is definitely a single market with few barriers.
