Government Involvement In the early years of American history, most political leaders were reluctant to involve the federal government too heavily in the private sector, except in the area of transportation. In general, they accepted the concept of laissez-faire, a doctrine opposing government interference in the economy except to maintain law and order. This attitude started to change during the latter part of the 19th century, when small business, farm, and labor movements began asking the government to intercede on their behalf. By the turn of the century, a middle class had developed that was leery of both the business elite and the somewhat radical political movements of farmers and laborers in the Midwest and West. Known as Progressives, these people favored government regulation of business practices to ensure competition and free enterprise. They also fought corruption in the public sector. Congress enacted a law regulating railroads in 1887 (the Interstate Commerce Act), and one preventing large firms from controlling a single industry in 1890 (the Sherman Antitrust Act). These laws were not rigorously enforced, however, until the years between 1900 and 1920, when Republican President Theodore Roosevelt (1901-1909), Democratic President Woodrow Wilson (1913-1921), and others sympathetic to the views of the Progressives came to power. Many of today's U.S. regulatory agencies were created during these years, including the Interstate Commerce Commission, the Food and Drug Administration, and the Federal Trade Commission.
