Why does there have to be a Number One or a New Number One?

Is it contrary to being thoughtful to believe that the U.S. is the only place on earth that one would like to live...but that there are some serious issues that are threatening our lifestyle and the future of our kids and grandkids? Can't we be the best and still agree that there are some issues that really need attention?

That's what I believe.

But if someone says "we're number one and that means we're number one in everything"...my reaction is that's complete nonsense.
