What Is America?
Ideally, America is a place where you get to make your own decisions instead of having them made for you by either your neighbors or a bureaucracy. In particular, it's a place where you have the right to hire foreigners, rent to foreigners, buy from foreigners, and sell to foreigners.
I have to mention that latter point because some people regard those rights as some kind of giveaway to the foreigners.
Addendum: Part II is up.
