What is one reason the American economy grew in the 1920s?

Technological progress led to mass production of goods, widespread use of electricity, new mass marketing techniques, availability of cheap credit, and increased employment. This created a large network of consumers in the United States, therefore causing the economy to grow.

in february 1787, congress decided that a convention should be convened to revise the articles of confederation, the nation’s first constitution. in may, 55 delegates came to philadelphia, and the constitutional convention began. debates erupted over representation in congress, over slavery, and over the new executive branch. the debates continued through four hot and muggy months. but eventually the delegates reached compromises, and on september 17, they produced the u.s. constitution, replacing the articles with the governing document that has functioned effectively for more than 200 years.
