The scene is a deliberate misunderstanding of what "greatest country" means. You can rattle off stats to support almost any point of view. It is easy to selectively make things sound better or worse than they are. What makes America special is that America is the only large country with a government system based on distrust of government. Our founding fathers saw rights as being granted by God, not government - the government only recognized (rather than denied) rights that existed anyway. The government, particularly the federal government, was divided, shackled and restrained to prevent it from trampling the states and the people. Most governments in world history approach it differently - with God-anointed kings, or populist dictatorships, or even in the case of elected governments, where rights are perceived as something granted by government. The practical effect of this is that the U.S. has a relatively small government and very strong economy. But if you are of an authoritarian mentality that values strong central leaders telling people what to do, America gives you conniption fits. You dislike the basis of America. You want to change it so it is more like all the other countries. So, you come up with stats that you think prove "America sucks" and you have an imaginary news anchor rattle them off, as if he is a brilliant and knowledgeable figure correcting an ignorant college student.

This is just a tribute.

But is America the best Continent?

It's not the best, considering that's a subjective comment...however objectively it is in a much better position then other countries.

Unfortunately, given Americas position as the melting pot of the world, we get the positives and negatives of many other countries. As a result of this, depending on the state of other countries and how many and what kind of immigrants are coming in, Americas overall position can vary considerably.

It never has been.

Obviously, it's never been the greatest

There's people who think it is?
