...unemployment is complicated. Switzerland and the Netherlands have high wages, but low unemployment rates; Spain and Poland have lower wages, but high unemployment rates. Eurostat (http://europa.eu.int/comm/eurostat) estimates that EU-25 unemployment was 8.8% in January 2005, as compared to 5.2% for the US and 4.8% in Japan.
Unemployment is a bit higher in the EU than the US because (1) semiperipheral regions like Spain, Portugal, and Eastern Europe with big agrarian workforces are included in the total count, whereas 2 million US prisoners are not, (2) the euro has appreciated 40% versus the dollar, putting a damper on EU exports, and (3) labor participation rates in the US plunged since 2000, but remained relatively stable in the EU.
