There must be a way for countries to drop out of the EU if they want to. I can name several countries that are dragging it down so much financially that they should be tossed out.
The Greeks are #1 on the list. They are currently blaming the Germans for their problems, even though the real problem is the widespread thievery of EU economic aid by the politicians, and the overall lazy and l greedy nature of the Greek people.
If Hungarians really want to drop out, I don't see anything stopping them.
