The USA isn't great because of our resources, nor our protection, in the past, from
invasion; Mexico and Brazil are in the a similar position yet haven't achieved anything. It is
a cultural thing. Even though the United States has problems with race, etc.., we
recognize it as a problem, and are working towards solving it through inclusion and
peaceful ways, not by exterminating the minorities.

The goal for every country should be to be more like the US in peace, wealth and
reasonableness.
