What was the government’s role in the economy of the late 19th century?

In the 19th century the government had little to do with the economy. They refused to control most businesses. They helped some with agriculture, and gave some financial support to companies building railroads. The federal reserve was founded in the early 19th century, but as the 20th century approached many more regulations were set in place. Large groups formed and this increased a large growth in the economy but the government had little to do with it.
