Okay, that's not decline, and not all of those figures are facts. Also, you seem obsessed with quantity of infrastructure built, which isn't really a great metric for measuring what you're claiming is happening.
The other poster with the analogy about a child's height is 100% accurate.
We've been surpassed in PPP, Global Trade, Industrial Output etc. China's steel production is 1 billion tons a year, the US 80 million tons. They poured as much concrete in the last 10 years as we poured in the 20th century. In just a few years we will be surpassed by GDP and witin 25 years China's GDP will be double the United States.
China's rise is not disputed.
