As concerning as that map looks you fail to understand the the US GDP has also
grown. Meaning, 20 years ago our GDP was 6 trillion and now it is 14.5 trillion. The Debt percentage is a higher now, but our economy has also doubled itself in the last 20 years.
So let me fill you in. The US growth from 2000-2011. $9.8 trillion- $14.1 trillion = 4.3 trillion
China's growth from 2000-2011. $1.2 trillion- 4.9 trillion. = 3.8
The US has a lot of external debt ($14 trillion) but the US gross is 3x more money with a population 3.2 x smaller.
The US is a powerhouse of industry still and gambling to build China's economy so we can advance on "their" market place and it's working. 2011 was the first year the US sold more cars in China then it did in the US.
Finally, China has grown too fast and we want to be there deeply rooted when that
bubble pops.
Never... Never, bet against the US.
