I don't know if this is troll or no, you can easily live rich & luxury life in most of the countries.
Especially Eastern European countries, Poland, Turkey, Russia or South America like Brazil, Argentina etc.
Not in turkey or russia. I lived in both of them and 200k usd is definetely not enough to live a luxury life.
You can only buy a moderate flat with 200k usd in cities like moscow - sankt petersburg - istanbul - izmir. And you would have to find a good job to keep living in these flats.
With 200k he can have an amazing live in Germany...Especialy if he could get social payment for flat.
He can buy greek citizenship than go to some easy work in germany forand 1 year and after that get free flat for alltime long and 200k will be enough money to be happy.
Work in Germany is realy nice and easy.
Not something like in usa,turjey,russia,china or else..
Learn german and willkomen
