Why must the US place high tarrifs and use quotas to restrict trade with foreign countries?

The U.S. may impose high tariffs and quotas on foreign trade to protect domestic industries from foreign competition, ensuring local jobs and economic stability. These measures can also be used to address trade imbalances and promote fair trade practices. Additionally, tariffs can generate revenue for the government and serve as a tool for negotiating better trade terms with other countries. However, such restrictions can lead to higher prices for consumers and potential retaliation from trading partners.
