Vienna is now the world’s most livable city (passing Melbourne), according to a recent short piece in The Economist. Their rankings consider some 30 factors related to safety, healthcare, education, infrastructure, the environment. Six of the top 10 are in Canada or Australia, and midsize cities do better than large. Of course it depends on one's taste, expectations, desires, and more to make a place livable.
Why Vienna? I remember someone saying Vienna without Jews is nothing special. There's a searing documentary, Vienna Is Different, made 50 years after the Anschluss, & the people still took no responsibility—we were victims not monsters, was their basic attitude.
Nonetheless, I want to hop on a plane ASAP for a long weekend, to Vienna. Or to Prague, Budapest, Dublin... anywhere!
