China's share of the world's manufacturing output by value-added was 2.4% in 1990, and 12.1% in 2006. In 2006 its biggest exports to the U.S. were electronic machines and equipment; that year the U.S. imported $288 billion from China, vs. $55 billion exported. The Economic Policy Institute estimates a loss of 1.8 million job opportunities since 1981 as a result of this trade deficit with China. Meanwhile, direct foreign investment in China from 2002-2005 totaled almost another $250 billion that didn't go to the U.S. either.
In 1980, American manufacturers produced 70% of apparel purchased in the U.S.; by 1990 it was down to 50%, and only 9% by 2006. America now only produces 1% of its citizens shoes; etc. for numerous other products.
"The China Price" points out that there is intense competition within China - its coastal export regions have over 1,000 clusters producing specific products such as ties, socks, microwaves, etc., and within those clusters manufacturers have hundreds of direct competitors. This is due to ease of entry - available start-up funds and assistance from Chinese officials eager to increase employment.
Chinese law limits overtime hours, requires a number of worker protections. Unfortunately, inspectors are typically overloaded, often corrupt, and frequently deceived by managers hiding factories that don't adhere to the rules. (These managers have also learned to deceive inspectors from American companies seeking to verify compliance with humane employment conditions.) At the same time, many workers will not stay if they don't get enough overtime to make the incomes they desire ("I didn't come here to sit!"), and fear of investing in government-mandated pension plans due to restrictions on their coverage.
And then there is the obvious pollution, especially from coal (producing a greater proportion of electricity than in the U.S.), and liquid effluents.
China's government is under enormous pressure from its citizens to provide jobs, particularly after the state-supplied sinecures have largely been eliminated. This, combined with even lower costs available in other nations (eg. Vietnam, India) do not bode well for America's "China problem" going away easily. (Common sens, plus Economic 101 tell us that it will continue until wage costs in China etc. roughly equal those in the U.S. In turn, that means we can look forward to eg. workers sleeping 12 to a room in factory-provided housing, and much reduced access to pensions and health-care - unless trade restrictions are imposed.)
The "bad news" about "The China Price" is that it often offers questionable or impossible statistics - eg. ". . . saved 80% to 100% . . ." (impossible to cut costs 100% - unless the product is delivered scot-free), "nearly one-third of the air over L.A. and S.F. can be linked to Asia" (what does that mean?) that damage the credibility of the book.
Bottom Line: "The China Price" explains why they are so price-conscious, and warns us that they're next move is likely to be into R&D, branding, and U.S. marketing (the "soft three" dollars of every four dollars spent in the U.S. for Chinese-manufactured products).
