The North American Free Trade Agreement (NAFTA) has brought benefits like increased trade and efficient automotive production. However, concerns about job losses and trade deficits have led to calls for renegotiation. While some jobs have been lost to Mexico, most job losses are due to automation. Renegotiating NAFTA to reduce the trade deficit and keep jobs in the US may not be achievable. Updating NAFTA could improve areas like dispute settlement, labor and environmental protection, and support for small businesses.
