From the UK Guardian. The article is in the business section but it is interesting that the author cites cultural issues as a problem.
The assumption is that the problems can be easily solved because the US is the biggest economy on the planet, the only country with global military reach, the lucky possessor of the world’s reserve currency, and a nation with a proud record of re-inventing itself once in every generation or so.
All this is true and more. US universities are superb, attracting the best brains from around the world. It is a country that pushes the frontiers of technology. So, it may be that the US is about to emerge stronger than ever from the long nightmare of the sub-prime mortgage crisis. The strong financial position of American companies could unleash a wave of new investment over the next couple of years.
Let me put an alternative hypothesis. America in 2011 is Rome in 200AD or Britain on the eve of the first world war: an empire at the zenith of its power but with cracks beginning to show.
The experience of both Rome and Britain suggests that it is hard to stop the rot once it has set in, so here are the a few of the warning signs of trouble ahead: military overstretch, a widening gulf between rich and poor, a hollowed-out economy, citizens using debt to live beyond their means, and once-effective policies no longer working. The high levels of violent crime, epidemic of obesity, addiction to pornography and excessive use of energy may be telling us something: the US is in an advanced state of cultural decadence.
