I don't think China will overtake the US. I don't think the US is a hyperpower, but certainly a superpower. My main problem with China is their growth rate. They are growing at an unsustainable pace..
I read around 8 articles just now about this and some of them bring up good points. I'm not sure if the telegraph is reliable, biased, etc as I have not encountered it, but they bring up good points
Also, the USA has the potential to overtake Russia in natural gas production, and Saudi Arabia in oil exportations within the next few decades. Because of this, the US will be a energy exporter, which I feel would be important for our economy.
The USA exports culture. When is the last time you heard of a famous Chinese song, movie, etc? Western culture dominates, and the USA contributes heavily to western culture. In fact, most of the highest grossing films are produced by Americans.
America's contribution to science and technology has been massive as you all know, and NASA is still the largest space agency in the world. Not to mention the many American private space companies such as SpaceX, and Planetary Resources.
America innovates a lot - Tesla Motors, Google, Microsoft, Apple, IBM, etc
Silicon Valley is undoubtedly the capital of innovation and technology.
The USA has a high quality of life, our poorest are not "poor" by global standards. Our hungry can get access to food from charities or through food stamps, our homeless have access to welfare. We still have many who are below the poverty line, however, our poor are better off then the poorest of Sudan.
America lacks socially, we are a "conservative" country by global standards sadly - we don't have universal healthcare, or a strong welfare state. However, I think our welfare system is superior to China's, and nevertheless I think the USA may not decline as a world power..
"Liberterianism is a mental disease. A national health crisis and a threat to the future of this country...Worse than the threat from terrorism, asteroids, disease and yes global warming.
It is mindless anti-government idiocy. If it isn't turned back I predict the end of this country as a world power. Simply put the need to educate our entire population like any sane country is sen as wrong by the cult that practice this foolish idiocy. So is simple workers rights, child labor and every other sane policy of the modern world."

"The world runs on individuals pursuing their self interests. The great achievements of civilization have not come from government bureaus. Einstein didn't construct his theory under order from a, from a bureaucrat. Henry Ford didn't revolutionize the automobile industry that way."
