This is the United States of America’s birthday. Sadly, many people think that Constitution Day not Independence Day is the birthday. There’s an important truth of social science here: countries create government, not the other way around. A nation needs certain institutions in order to function. Government is one of those.

In America the confusion arises because it was a quasi-government, the Continental Congress, that issued the Declaration of Independence. It was the tool that the nation used to establish itself. There were other ways of doing this. It is difficult to think of any way that were as simple or as effective as this one was.
