When is the United States going to make it clear, once and for all, U.S. jobs and workers are not for trade?

Because Congress finally stopped Mexican trucks from entering the United States, which obviously would labor arbitrage U.S. truckers in addition to security and safety issues, Mexico is retailiating by tariffs.

Mexico slapped tariffs on 90 American agricultural and manufactured exports on Monday in retaliation for Washington's move to block Mexican trucks from using U.S. highways.

Mexican Economy Minister Gerardo Ruiz said about $2.4 billion worth of exports from 40 U.S. states would be affected and that his government would soon publish a list of them.
