Tariffs are controversial because they pit national protection against global equity. Supporters argue that imposing tariffs helps safeguard local industries and employment, ensuring that domestic workers are not undercut by competitors benefiting from lax labor or environmental regulations abroad. This, they contend, maintains a level playing field where all producers compete under similar standards. Such measures are seen as necessary for promoting economic fairness, by protecting communities from the adverse effects of unrestricted globalization, even if critics view them as market distortions that may complicate global cooperation.
