Why didn't American industry suffer the impact of foreign industrial products in the early stage of development?

The early stage of American industrial development was not impacted by foreign industrial products, which can be attributed to the following reasons:

1. Geographical factors:1At the beginning of the 9th century, the geographical distance between the United States and industrialized countries such as Europe was far away and the transportation was underdeveloped, which limited the ability of foreign industrial products to enter the American market.

2. Protectionist policies: At that time, the US government adopted a series of protectionist policies, such as high tariffs, import restrictions and subsidies, to protect the development of domestic industries and block the competition of foreign industrial products.

3. Self-sufficient economy: In the early days, the United States mainly relied on agriculture, not industry. Self-sufficiency in agricultural production reduces the demand for imported industrial products and is conducive to the development of local industries.

4. Technological innovation and abundant resources: The United States has a vast territory, abundant natural resources and advanced technological innovation capability, which makes local industries have sufficient advantages to meet the domestic market demand.

5. Labor supply:1At the beginning of the 9th century, the population of the United States grew rapidly and the labor supply was sufficient, which provided a strong impetus and market demand for industrialization.

It should be noted that although it was not impacted by foreign industrial products at first, as time went on, with the growth of global trade and the development of technology, American industry gradually faced competition and impact from other countries.
