My point is that our lives here have improved too, but still the sentiment isn't that positive, rightfully so.
Also China isn't a third world country, it's a pretty big player in the global scale and yet the condition of his population are on par or lower than what you can find in the "west".
And that doesn't sound too me like a big different situation fron what we have, let alone a better one. Then how is the perception of what's going on that different?
This should be improved with adding more countries, like Russia, then comparing with other important data, like freedom of expression, to be somehow relevant to any discussion
