It is difficult to say whether protectionism is good or bad since every nation is introducing it to protect a domestic interest that is threatened by what is being imported. At times, it is possible to justify protectionism for the simple reason that it will serve a given purpose. Governments would be benefited from the income generated by introducing a high tariff on a given product or sector, for example, and that might be another advantaged translated to it, considering that such measures could give tax payers a relief. If governments have enough revenue from imported good, they will demand lower taxes domestically.
