The fault might lie in the way statistical information is collected and presented. Apple, for example, is a US corporation. It reports its worldwide earnings to the IRS. Its manufacturing is counted as US manufacturing as it is a US corporation. However, Apple doesn't produce a single computer in the US. They are produced in China. The employment that Apple reports is in China. The Chinese are employed by an American company, but they are not Americans. The Chinese incomes that Apple provides do not support the American consumer market or provide the tax base for cities and states. The Chinese incomes do not provide ladders of upward mobility or careers for Americans.
The wages Apple pays are in China. The consumer incomes and GDP that it generates are in China. When Apple's computers come back to America to be sold they come in as imports. But Apple's manufacturing and employment are reported as the output and employment of an American company.
When statistics and the methods by which they are compiled were put into effect, countries did not offshore their production for their domestic markets. Foreign investments were made for selling abroad, not for selling in the home market. With the advent of offshoring, counting the employment and output of US firms that are producing abroad for their domestic market as an indication of the strength of US manufacturing is very misleading. Apple, for example, has done more to boost China's GDP than to boost America's GDP. This is true of every US corporation that offshores its production for US consumers.
In recent years the percentage of the work forces of large US corporations that is foreign sourced has risen rapidly. Some of the overseas hiring reflects traditional foreign investment in which a company builds abroad in order to sell abroad, but much of the hiring reflects offshored production for US markets.
The US has been able to survive the large trade deficits produced by jobs offshoring, because the US dollar is the world reserve currency. Being the world reserve currency, the US does not have to earn foreign currencies with exports in order to pay for its imports. However, as these trade deficits persist and the buildup of foreign holdings of dollar paper assets rises, there is a diminishing willingness of foreigners to trade real goods and services for financial assets denominated in a fiat currency whose value is diminishing with the ever-growing supply.
Thus, the basic notion of globalism -- that a country's corporations can produce goods and services in any country for home markets -- is false.
Walsh is correct that China is not to blame for the decline in US manufacturing. Offshoring is to blame and, thus, the blame lies with US corporations, policymakers, and the economists and financial media who shill for "globalism." The decision was made to sacrifice the US economy to the short-term profits of the few. A country so poorly led can do nothing but decline.
