Manufacturing jobs will go whever it makes fiscal sense for them to go. As heyheybooboo stated, there is no population explosion in the USA. The last statistic I saw said that for every 67 babies born in the US, 357 are born in China. However, that is about the only thing he DID get right.
2) China manipulates it's currency? No big surprise, so does the USA.
The United States manipulates it's currency on a very very limited basis. The Chinese Government engages in wholesale lockdowns of their currency value to keep it where they want it to be.
To quote our state department:
Exchange rate flexibility, which garners most of the attention, is first and foremost in the China's interest. With a rigid exchange rate, China's monetary policy is effectively set by the Federal Reserve. China must absorb large inflows of capital and can't raise its own interest rates without attracting even larger flows. Greater exchange rate flexibility will strengthen the ability of Chinese monetary policy to help assure sustained growth, avoiding the boom-bust cycles that have characterized Chinese growth to date. Greater ability to control domestic interest rates will also lead to more efficient and prudent financial intermediation, and help avoid credit-fueled investment booms and resulting buildups of non-performing loans.
In fact, in July of last year, the Chinese leadership publicly committed to greater exchange rate flexibility and Premier Wen reaffirmed that commitment just last month. Our engagement with China on exchange rate policy is now not about "whether" but about "how quickly." To date China's progress has been far too cautious. The obstacles are no longer technical; China could easily move more rapidly towards greater flexibility. It should do so now.
3) China uses cheap labor - The USA uses cheap labor (i.e., Hispanics).
First, China's pool of "Cheap" labor is over 1 billion people. The "hispanics" you're talking about (I'm assuming) are illegals working for under minimum wage, and as such make up an incredibly small portion of laborers in the US. In addition, they are not working manufacturing jobs - they are working at manual labor jobs.
4) The growth in jobs in China is primarily centered on skilled, technical manufacturing jobs that were formally in the USA.
The growth of jobs in China is certainly not center on skilled technical manufacturing jobs. It is centered on menial labor jobs where people sit at a table for 12 hours a day and put a specific bolt into a specific hole, generally under absolutely horrible conditions.
6) There are skilled labor shortages in China, too.
There are some skilled labor shortages, but they are being filled incredibly quickly. Chinese colleges graduate more engineers in one year that US colleges graduate in TOTAL. In positions where they don't have expertise, they are hiring Americans for the short term. Doctors, Vets, Engineers, all are being flown over there for a year to 'train' the chinese. I know, because 3 of my family members are over there right now.
7) There is an infinite resource of unskilled labor in China but costs are rising 10%/year.
8) Wages in China are rising close to 25 percent a year for skilled labor in many industries.
Again, unskilled labor in China is what's currently driving their economic boom.

More than twenty-five years have passed since China began its transition to a market economy, and China has seen its standard of living surge. The growth of China's income per capita is much faster than that of any region in the world, and especially noteworthy considering the country's size and extreme regional differences. Rural poverty has declined significantly, dropping 89% from 1978-2002.
10) The US dollar has gained around 18% against the Chinese Yuan since mid-2005.
Gained. Which means it's that much cheaper to manufacture in China - exactly the point he made with his reference to manipulation.
In answer to the original poster - no. If the US were to ever decline, it would be over a course of generations. Our economy is so tightly tied to others because of the money and power we wield that they will help to keep us afloat in bad times. Look what our financial market mess caused - a global recession.
