What are the economics and trades in 1912?

Answer: The US economy has been expanding extensively.

Explanation:

The impact of the US economy just before the outbreak of World War I was intense and spread in every direction of the world. The United States was the largest exporter of cotton, wheat, and some other agricultural products. The development of the industry has made US goods competitive and much cheaper than the European market.

Leading US companies such as International Harvester, Singer, Du Pont, Bell, Colt, and Standard Oil have been technologically equal or often better than any in the world. During this period, New York, which was the leading economic port of the world, distinguished itself and distinguished itself as the financial center of the united states. During this period (specifically in 1912), US military intervention took place in Nicaragua, all to protect the economic interests of the united states.
