What Happen to the Times of Beauty of the Beast?

As I re-watch scenes like this http://youtu.be/MVovQfq7U0w I'm rather sad how I'm not living in times like this. What happen? A time where societies work with nature, worship God, and friendly to each other. Yes I know there was racism amongst foreigners and colored individuals but imagine this, the things of that time with our ethics. Man, that's a utopia!
