Proponents of NAFTA in the United States stressed that the pact was a free trade agreement and not an economic community agreement.  The free movement of goods, services and capital did not extend to work. By proposing what no comparable agreement had attempted to open up to a “great third world country” – NAFTA avoided the establishment of a common social policy and employment. The regulation of the labour market and employment has remained exclusively due to national governments.  Supporters supported NAFTA because it opened up Mexican markets to U.S. companies like never before. The Mexican market is growing rapidly, which promises more export opportunities, which means more jobs. However, proponents have struggled to convince the American public that NAFTA would do more good than harm. Their main efforts have been to convince citizens that all consumers have as wide a choice of products at as low a price as possible, which means that consumers would be the main beneficiaries of lowered trade barriers. The U.S. Chamber of Commerce, which represents the interests of small businesses, was one of THE most active supporters of NAFTA and organized small and medium-sized business owners and employees to support the agreement. This support was essential to counter the efforts of organized work to put an end to the agreement. From June to the end of August 2018, Canada was sidelined due to bilateral discussions between the United States and Mexico.
 On August 27, 2018, Mexico and the United States announced that they had reached a bilateral agreement on a revised NAFTA trade agreement, which includes provisions that would boost U.S. auto production a 10-year data protection period against generic drug production on an expanded list of products enjoyed by pharmaceutical companies. , particularly U.S. manufacturers of high-quality bionological drugs. , a sunset clause – a 16-year expiry date with periodic audits over 6 years to eventually extend the contract for an additional 16 years, and a high de minimis threshold, where Mexico increased the de minimis value of US$50 in terms of duty-free and tax-free online purchases to $100.   According to an August 30 article in The Economist, Mexico has agreed to increase the rules of origin, which would mean that 75% of a vehicle`s components must be manufactured in North America, as opposed to the previous 62.5%, in order to avoid tariffs.  Given that automakers are currently importing cheaper components from Asia, consumers would pay more for vehicles under the revised agreement.  In addition, approximately 40 to 45 per cent of vehicle components must be produced by workers earning at least $16 an hour, as opposed to the current $2.30 per hour that a worker earns on average at a Mexican auto plant.   The Economist described this as a “Mexican car construction in a straitjacket”.  The kick-off of a North American free trade area began with U.S. President Ronald Reagan, who made the idea part of his 1980 presidential campaign.
After the signing of the Canada-U.S. Free Trade Agreement in 1988, the governments of U.S. President George H.W. Bush, Mexican President Carlos Salinas de Gortari and Canadian Prime Minister Brian Mulroney agreed to negotiate nafta. Both submitted the agreement for ratification in their respective capitals in December 1992, but NAFTA faced considerable opposition in both the United States and Canada. The three countries ratified NAFTA in 1993 following the addition of two related agreements, the North American Worker Cooperation Agreement (NAALC) and the North American Environmental Cooperation Agreement (NAAEC). NAFTA has not eliminated regulatory requirements for companies wishing to act internationally, such as rules of origin and documentation obligations, which determine whether certain products can be traded in the c
