Greece is a very rich country: people can afford to put more cars on the road than the government can manufacture license plates for.

Greece is a very poor country: the government can't even afford to manufacture enough plates for the cars that are getting added.

Greece is a very short-sighted country: they can't even put a plan together that prevents a license plate shortage.

Meanwhile, there's a possibility that I won't be allowed to drive my new car for lack of a plate for it.
