The number of Greek electricians driving Porsche is not very high. Also the German exports to Greece are also not that big (from both sides).
In reality Greece imports from all over the place. It also imports a lot of energy sources. It has a huge military with costly imports (parts from that also from Germany). Also the money does not come especially from Germany. If you look at the banks, they are from France, Italy, Germany, US, etc.
Avoiding paying tax is a sport - especially for some of the very rich families in Greece.
There are several other reasons.
There are a lot of people in Greece who work hard and a lot of people who don't work that hard. There is a huge and relatively unproductive government sector for example.
How many hours people work is really not that important. In Germany people may work fewer hours, but the work is much more focused. After the necessary working hours many workers actually go home. In many other countries workers spend more time at to workplace without being productive. Also there are large parts of the industry which have lots of robots. For example in car manufacturing you find 10000+ robots working. You would find that level of automation only in a few places on this planet. Not so much in Greece.
Larisa, which has about 250,000 inhabitants, is the capital of the agricultural region of Thessaly in central Greece.
Larissa “is the talk of the town in Stuttgart, the cradle of the German automobile industry, and, particularly, in the Porsche headquarters there”, since it “tops the list, world-wide, for the per-capita ownership of Porsche Cayennes”.
