This is a pretty open question of course, as there will be different answers for different groups of people, and different kinds of ways in which a country can be good/bad.

I live in Germany, and while it's a country with many, many flaws, I can't say that I hate the country because, frankly, there's not many places I'd rather live. But of course, I'm a middle-class suburban white girl, the systems here largely exist to benefit me. For other groups of people it might be different. If I had to move to another country right now, Finland would probably be my first pick. I'm interested in China for a number of reasons, but I doubt that living there would ultimately be better for me.

So yeah, it's kind of a purposely vague question, I'm curious on what you think.
