I disagree, Brian. The US is the worlds only superpower right now. And it is engaged in attempting to spread the benevolent hegemony of Pax Americana to the rest of the world. If the US succeeds, a version of history will be written and passed to others either by guns or diplomacy. In the "civilized" world, the education systems will teach it and the generations will be indoctrinated to view the US with goodwill.
If our country fails, things could get ugly. Look at how harshly British Colonialism is treated by "historians". All of the blemishes are fully examined so that it looks like there is nothing but blemishes. Reading that version of "history" is going to paint the Brits as an expansionistic, agressive, oppressive, stratified, jingoistic, racist, regime hell bent on world domination.
Are the British evil?
Like it or not, I think we are destined to be painted like this. The sun never sets in the empire of the US, but just like the British, we will not be able to maintain it. Our debts are rising astronomically, our currency is devaluing and more and more people are dropping off into poverty, our standard of living is dropping, and our military is finding it nigh impossible to procure resources for our out of control consumption.
Hopefully, we do not have the twin calamities of "WWI" and "WWII" that effectively put the nails in the Pax Brittania coffin. Hopefully, the US declines peacefully, we slowly alter our culture to live more sustainably and equitably, and we begin the process of pulling the tendrils of hegemony back to let people live as they may.
The alternative is WWIII. Our enemies will be China, Russia, and India. With the state of our financial system and resources at home, we'd never be able to sustain such an effort and Pax Americana will be forcibly put in the history books alongside Pax Brittania.
So, is the US evil? Not yet, IMO. Our society is on a direction that has been taken before by others and they were painted as evil. Can we change before it's too late? Is it already too late? The answer to both of these questions in regards to both "Pax" examples above lies in who controls the money.
