The correct answer is II. This argument is in the best interests of the people they represent.
Explanation:
Trade unions in developed countries tend to support trade restrictions, because products made in countries with lower wages are generally cheaper than those made in those developed countries. For example, a pan loaf that costs about 3 dollars in the United States, can cost about 0.75 dollars in Mexico. Therefore, import value, including tariffs, is less than that of national production. This means that, if barriers to trade are not established, many workers lose their jobs due to the fact that national production is terminated due to the possibility of importing said products.
