Oh so you have no proof of your claims about them being lazy? What a surprise.
I have actual proof of my claim. It's not conjecture. Greece has many problems, laziness in the workforce is not one of them.
No, you don't have proof - as was the case before, you have numbers that you don't understand and don't know how to use. Whether your using Eurstat or OECD or whatever, a direct comparative analysis can't be made. It's really simple but seems to be well over your head.
There are differing methodologies for collecting the data and different premises by which a country counts actual work hours.
ALL of the primary databases that collect such data warn of making such comparative analyses.
If you really want to educate yourself, look into internal and external validity as well as generalizing when it comes to basic (and yes, this is basic) research methods.
I lived in Greece for a couple of years. They have the equivalent of a Mexican Siesta (forget the name now), but basically the whole fucking country comes to a crawl in the afternoon. Hell, I can remember Greek soldiers lounging at cafes on the beach for hours at a time. All but guarantee that's be counting as part of their work day. And being along side of them, I know they didn't stay late and make up the time.
When you're capable of providing a study that utilizes the same methodology in all countries, does not rely on each country to "self-report", and meets the basic criteria of objectivity - then you'll have "proof".
Since most of this is way, way, way above your head - I'll simply conclude with -
you're wrong, as usual.
