Also taking into account GDP divided by population, that implies Greeks get less done per hour than Belgians. To call Southern Europeans ‘lazy’ would be a bit much, but I do think the numbers support that they have a different work ethic from Northern Europeans.
I live in the Netherlands, where people work 30 hours a week on average. Yet, the Netherlands is one of the most productive countries in the world, if GDP (PPP) is to be believed[1]. (Then again, on that chart, Greece is placed only one spot lower, so that may not be the best source.)
