While it’s true that an open marketplace benefits the vast majority, there may be some people who lose out because of increased competition or imports from abroad. For this reason, governments should take action to provide financial assistance and job training for those who are negatively impacted. In addition, some restrictions in trade may be needed to protect industries that are vulnerable or to prevent unfair business practices like dumping.
While I agree that some trade restrictions are necessary, I also believe the main goal is to remove all barriers and allow free markets wherever possible. It would allow countries to benefit from the global economy without having their economic interests compromised.
