It has been argued that tariffs harm consumers and benefit producers. Justify this argument.

Answers will vary. Governments favoring protectionism can implement different trade policies, such as tariffs, subsidies, quotas, and antidumping actions. These policies in turn can help domestic firms stay competitive with foreign firms; however, they are not without repercussions.
A tariff is a tax levied on goods as they cross the border of a country, whether coming in or going out. In general, import tariffs are meant to protect domestic production by raising the price of imported goods in order to ease competition with domestic industries. Tariffs produce revenue for the domestic government. Generally, import tariffs lead to increased prices for consumers and easier conditions for domestic manufacturers. In other words, tariffs harm consumers and benefit producers by creating artificial economic inefficiencies. Import tariffs are usually more common than export tariffs.
