I would say Singapore because it is small but very wealthy and safe. It's very beautiful and modern, and it's one of the best places to travel to 

I’ve only been in Europe and South America, but it seems to me that if you’re talking about freedom of speech, natural beauty, and the number of opportunities for personal success, the answer would be the United States of America.  It is the country where most people in the world want to live.  Canada would come in second place, I think.

For me,  a country without violence,  bandits and corruptions with beaultiful places and a lot of leisure opitions. It would be the best country of the world! 

I agree with you. 

There is no best country in my opinion. Developed/western countries have different types of problems and no country is perfect.
