Apparently , somebody in the Greek government wants tourists to spy on Greek business people.
The article names nightclub owners and medical practitioners as the kind of people the government wants to crack down on .... but every time a newspaper or broadcast brings up the REAL tax cheats -- the super-rich Greeks, fleet owners, major shareholders of giant corporations, major exporters, the "1%" of any country that always lives well (and those in Greece have been sending their €€€€ to Switzerland forever) ... then the government falls silent.
Many of the Greeks I know pay taxes faithfully and THROUGH the NOSE... People such as a Gymnasium (High School) department head who had his salary cut 25% in one year, and a govt. worker, head of the water department for a whole island, worked 40 years and at age 64 was told his pension was cut to less than €400 per month ... and the small hoteliers (8-12 rooms) who no longer can have helpers, but must clean all the rooms themselves ... and the owners of small tavernas who do the cooking, table-waiting and their kids sweep the floors. I for one am not going to rat on a taverna owner like that if he hands me a written bill instead of a tax-recorded bill. When the Govt roots out the corruption in its OWN ranks, that's when the revenue will increase.
