A common maneuver applied by the advocates of protectionism is to tunnel or fixate on specific imbalances which they use as basis to call for trade restrictions (otherwise known as the fallacy of composition).
Take for instance the debate over China’s role in the US economy, where Chinese imports have been alleged as ‘stealing’ US jobs.
From Walter E. Williams
Let's look at the magnitude of our trade with China. An excellent place to start is a recent publication (8/8/2011) by Galina Hale and Bart Hobijn, two economists at the Federal Reserve Bank of San Francisco, titled "The U.S. Content of 'Made in China.'" One of the several questions they ask is: What is the fraction of U.S. consumer spending for goods made in China? Their data sources are the U.S. Census Bureau, the Bureau of Labor Statistics and the Commerce Department's Bureau of Economic Analysis.
Hale and Hobijn find that the vast majority of goods and services sold in the United States are produced here. In 2010, total imports were about 16 percent of U.S. gross domestic product, and of that, 2.5 percent came from China. A total of 88.5 percent of U.S. consumer spending is on items made in the United States, the bulk of which are domestically produced services – such as medical care, housing, transportation, etc. – which make up about two-thirds of spending. Chinese goods account for 2.7 percent of U.S. personal consumption expenditures, about one-quarter of the 11.5 percent foreign share. Chinese imported goods consist mainly of furniture and household equipment; other durables; and clothing and shoes. In the clothing and shoes category, 35.6 percent of U.S. consumer purchases in 2010 were items with the "Made in China" label.
Much of what China sells us has considerable "local content." Hale and Hobijn give the example of sneakers that might sell for $70. They point out that most of that price goes for transportation in the U.S., rent for the store where they are sold, profits for shareholders of the U.S. retailer, and marketing costs, which include the salaries, wages and benefits paid to the U.S. workers and managers responsible for getting sneakers to consumers. On average, 55 cents of every dollar spent on goods made in China goes for marketing services produced in the U.S.

Mercantilists have been arguing from China’s niggardly 2.5% share which makes their entirely ridiculous.
And as pointed out earlier, despite the deepening trend of globalization, the US economy, whom supposedly represents the vanguard of free market capitalism, remains virtually a closed economy.
Yet such argument shouldn’t be seen in the light of merely the share of imports but rather from the social, economical and ethical merits.
As the great Ludwig von Mises wrote,
What generates war is the economic philosophy almost universally espoused today by governments and political parties. As this philosophy sees it, there prevail within the unhampered market economy irreconcilable conflicts between the interests of various nations. Free trade harms a nation; it brings about impoverishment. It is the duty of government to prevent the evils of free trade by trade barriers. We may, for the sake of argument, disregard the fact that protectionism also hurts the interests of the nations which resort to it. But there can be no doubt that protectionism aims at damaging the interests of foreign peoples and really does damage them. It is an illusion to assume that those injured will tolerate other nations' protectionism if they believe that they are strong enough to brush it away by the use of arms. The philosophy of protectionism is a philosophy of war. The wars of our age are not at variance with popular economic doctrines; they are, on the contrary, the inescapable result of a consistent application of these doctrines.
