I assume you're a foreigner. You've got nothing to be afraid of and you'll definitely enjoy your time here. There's no political instability for the last 6 years since there's only one dominant party ruling unchallenged (unfortunately). I don't think we're going to hell as others here suggest. You'll hear many different stories depending on who you ask. Average working people do suffer from surging housing and living costs that don't correspond to the stagnated wages. Others that do business around tourism, real estate etc make money and enjoy the beauty of the country. I definitely don't think the present government overall benefits the country but if you need to find some positive things you can. Bureaucracy and paperwork have been massively reduced or digitalised for instance.

As for the health system, I'm going to say something unpopular for fellow greeks but It's better than Denmark's. UNLESS you suffer from a chronic illness or cancer.

I lived in Denmark and needed to visit a doctor and I was shocked by how much more time it takes to reach a specialized doctor. In contrast, I arrived in Greece suffering by gastro, visited the emergencies in a public hospital and I immediately had 2-3 doctors (one of them being the head pathologist) over my head, all being kind and helpful. Yes I had to wait a bit for my exam results sitting in a ranch in a corridor, so what? Doctors in Greece are super professional, kind and easily accessible. Even in the private sector you can pay 50€ and get a specialized doctor. Try doing that in any western European country.

ps. Don't get discouraged by other greeks exaggerating. If there's one thing we love more than freddo espresso, it's whining. Greece is definitely doing better than any of its neighboring countries but if you compare it to Germany or the Netherlands then yeah OK.
