While I find it funny and I like those jokes, I think your comment implies a bit of ignorance. You should look for a list of countries ordered by their GDP (PPP) per hour worked. Spain's productivity is a bit higher than Japan's (I'm not an expert, so maybe there are more technical data to check out). Here you have a couple of links:
