Our national Trade Policy is inherently broad in scope, and it requires an equally broad brush to highlight those aspects that are detrimental to average Americans.
Nice try, but no cigar. Our "national trade policy", as such, is a mishmash of legislation resulting from congressional favoritism (MFN status) and outright vote-buying (commodity price supports and import quotas). Its breadth is not the problem - its purpose - is. In attempting to benefit some classes of Americans at the expense of others, trade regulations frequently hurt our consumers by limiting choice, artificially raising prices or limiting supplies, and (ultimately) by restricting competition.
American consumers benefit greatly by having access to inexpensive Chinese goods. They may purchase these or not, dependent on quality and the availability of alternatives. Consumers do not benefit, however, from price supports that make American goods noncompetitive but buy the votes of sugar producers in Florida or corn growers in Iowa.
