Answer:
In 1992, presidential candidate H. Ross Perot said that signing the NAFTA agreement would produce a "giant sucking sound" in the United States. He meant that NAFTA would make jobs in the United States go to Mexico, where laboral costs were lower, thus producing unemployment and poverty in the United States. In view of the events, 17 years later we can affirm that the fears of H. Ross Perot were never confirmed.
