Prove that there was an “American industrial miracle” in the USA in the 19th century.

What happened in the United States in the 19th century is commonly called the “American industrial miracle”. This name was given to the events of this period for a reason. But there were all the prerequisites for this. The fact is that after gaining independence from England, the United States began to actively develop. The country jumped from the slave system immediately to the industrial one and this gave its results. Since the country had democracy and freedom of action, people who had a lot of capital began to invest and earn money, which led to the rapid growth of industrial enterprises.
