A new name for the Americans

I was chuckling my way through John Shepherd’s amusing letter on the follies and foibles of my fellow Yankee gringo Americano devils when one sentence leaped out and smote my brain pan: “Will the American people finally stop calling themselves the American people?”
John has a point. I have long been dismayed by the habit of some of my fellow countrymen, mostly rednecks, of thumping their chests and braying about the virtues of the “Amurcan pipple”. Citizens of the United States are guilty of hogging a name that properly designates the citizens of not one but two entire continents. Everybody living from the northernmost tip of Canada to the southernmost tip of Chile is an American. What term, then, should we use to designate the citizens of that roughly rectangular slab of territory that lies south of Canada and north of Mexico?
This question has long agitated my tiny brain. Our country is called the United States. “United Statesians” sounds awkward and clunky. “United Staters” isn’t much better, and in fact it should read “United Statesers”, which is even worse. 
The best solution I can think of is to revert to our country’s acronym, USA, and call ourselves Usans, pronounced “Yoosans”. But I have no authority to make such a change, and urge the formation of a national commission to decide this vital issue.
There is also the question of what to name The Wall.
