Tariffs

Import tariffs basically put domestically produced items at a huge competitive advantage over foreign produced items in the domestic market. Tariffs make sense when it comes to protecting or fostering domestic industry (whether it be because of the workers or some national interest in domestic production). They are more efficient than regulations and rules and can raise revenue to boot.

Of course, the big downside is that they lead to higher consumer prices and can hurt exports if there are retaliatory tariffs. They also lead to less economically efficient outcomes on net. The thing is that economic efficiency and low consumer prices, while desirable, aren’t the only things that matter. So there are situations where tariffs are worth the cost.
