The passage is chiefly concerned with:
arguing against the increased internationalization of United States corporations
warning that the application of laws affecting trade frequently ha unintended consequences
demonstrating that foreign-based firms receive more subsidies from their government than United States firms receive from the United State government
advocating the use of trade restrictions for “dumped” products but not for other imports
recommending a uniform method for handling claims of unfair trade practices
warning that the application of laws affecting trade frequently ha unintended consequences
In the first sentence of the passage, the author characterizes the preoccupation of many United States companies with the search for legal protection from import competition as unfortunate. Then, the author explains that the “quest for import relief has hurt more companies than it has helped”. The third paragraph discusses one situation in which United States companies might experience such injury-when import relief laws are used against foreign subsidiaries of United States company and the last paragraph provides a specific example of this situation. Thus, it can be inferred that the author’s primary concern is to warm about possible unintended negative consequences of applying trade laws.
