Geographically, North America has very mild climates with a wide variety of ecosystems which allow for many different species of animals, comfortable living, and of course industry.
Culturally, America is the most diverse country on the planet with a strong social work ethic and sense of individual freedoms. American culture is a melting pot of many of the best parts of other cultures and that allows for citizens to experience many different ways of life early on. Also of note is that a central part of American culture is the lack of social status; everybody is equal to everybody regardless of money or position, and we find it insulting when someone thinks they are better than us.
Industrially, America has contributed much of the technological advancements we have today. This is in part due to the freedoms we have here, prompting many of the finest minds from around the world to come here (Telsa, Einstein, etc).
Militarily, America has the strongest military on the planet, which not only holds a vast nuclear arsenal that assures other countries won't use theirs, but also has some of the most advanced weaponry available for mass production. Aside from that, the US military is a force of
millions, and is manned entirely by volunteers, unlike several countries around the world.
Governmentally, America's system is generally fair compared to other countries. Everyone has the same rights, everyone abides by the same laws, and freedom of expression is just natural. Presidential elections are not rigged, everyone has the right to vote, and we were one of the first modern countries to do it.
Humanitarian-wise, America contributes a lot of resources to providing aid to those in need, whether it be from natural disasters, oppressive regimes, terrorism, or whatever.
Comedically, American humor is considered top-notch when done right. Just throwing that out there.
Now, don't get me wrong, there are a lot of bad parts of the USA to deal with (though IMO the benefits far outweigh the detriments), but the OP didn't ask about the bad stuff.
