Will the high tariff wall in the United States affect the total economic output of the United States?

The United States, called the United States of America, is an immigrant country, among the developed countries. Their mother tongue is English. As a capitalist country, after two world wars, the United States and other allies won the final victory together. After the disintegration of the Soviet Union, the United States became the only superpower in the world, and it was at the world's leading level in the fields of economy, industry and culture.

However, in recent days, the United States has issued news of raising tariffs, which is not good for its own country and other countries.

First of all, raising tariffs is not good for the US economy. Due to the increase in tariffs, the price of imported goods in the United States will increase, thus eliminating the enthusiasm of consumers outside the United States to buy their goods, making the sales of imported goods in the United States decline, and there may be unsalable goods.

Second, raising tariffs is not good for cooperation between the United States and other countries. This tariff increase in the United States has been strongly opposed by the European Union and other countries. This situation is not conducive to exchanges and cooperation between the United States and other countries, which reduces the psychological credibility of Americans in other countries and makes cooperation impossible.

Third, raising tariffs is not good for Americans. As a result of raising tariffs, domestic prices in the United States will also rise. If wages remain the same, prices will go up, and then the standard of living will drop. Therefore, civil strife may occur in the United States.

Trump will raise tariffs because he has the mentality of "a trade war is easy to win", but he doesn't know that such a result will only "harm others and not benefit himself" and will only end in failure.
