It might sound lame, but my recommendation for the USA is for people to learn the Federalist Papers by James Madison, Alexander Hamilton, and John Jay in order to gain an appreciation for the unique gift of the Constitution of the USA. I mean go through the Federalist Papers from start to finish.
I MEAN INSTEAD OF "AMERICAN HISTORY", LEARN WHAT AMERICA IS ALL ABOUT IN THE FIRST PLACE. History is so easily distorted according to what ones agenda is. After all, it would be like reporting on N.Y. City. To show your agenda is right, you do not even have to lie. All you need to do is selectively report the incidents that fit your narrative. [I mean lots of things happen every day in a city with millions of people. What you report on, depends on what you want to show.]
But the one flaw in the Constitution is the desire of people to get other people's stuff. If you bring into the USA enough people that hate the rich, and do not want to work to better themselves, but rather to take away from those that have worked, then nothing can save the situation.
