...they as citizens are exceptional by extension? Donl they think they are better than people of other countries?
I feel like the answer is "yes" and that's hysterical.
It is our system of government that is exceptional.
That has had, at least in the past, a very healthy effect on the American people, but, mostly the answer to your question is mostly no.
Also, hint: If you are asking a question of people who are very different than you, don't include your guess and then ridicule your enemies based on your guess as to what they would say.
It makes you look like a fool.
The people are exceptional, too. We are one of, if not THE most generousy nations in the world.
I strongly suspect that comes at least in part from the fact that our government does not, or at least did not seek to run our lives.
A subject of an all powerful government, allowed to keep a portion of his money, is not in a place to feel empowered or to be generous.
An American, free to make his own way, in a free land, has traditionally been more generous and apt to help his fellow man.
The stereotypical BARN RAISING, is the iconic example.
A farmer could not raise a barn by himself. His neighbors would come on their own to help.
They were not told to. They were not directly compensated for their efforts.
But the knowledge was that when they were in a similar place, the community would rally to help them.
That was America.
Now we have government and government programs.
