The "a better tomorrow" is a bit bland to me, but it's no worse than "The American Way", which is about as vague as you can get. What is "The American Way"? And it was added during a time of war when there were enemies perceived everywhere, so it was clearly a form of propaganda. And this isn't the first time this approach has been taken with the character. There have been multiple attempts over the years to expand Superman's scope to be more global, but they have mostly fallen flat due to poor execution.
Why is it so?
