As the American economy matured in the 20th century, however, the freewheeling business mogul lost luster as an American ideal. The crucial change came with the emergence of the corporation, which appeared first in the railroad industry and then elsewhere. Business barons were replaced by "technocrats," high-salaried managers who became the heads of corporations. The rise of the corporation triggered, in turn, the rise of an organized labor movement that served as a countervailing force to the power and influence of business. 

     The technological revolution of the 1980s and 1990s brought a new entrepreneurial culture that echoes of the age of tycoons. Bill Gates, the head of Microsoft, built an immense fortune developing and selling computer software. Gates carved out an empire so profitable that by the late 1990s, his company was taken into court and accused of intimidating rivals and creating a monopoly by the U.S. Justice Department's antitrust division. But Gates also established a charitable foundation that quickly became the largest of its kind. Most American business leaders of today do not lead the high-profile life of Gates. They direct the fate of corporations, but they also serve on boards for charities and schools. They are concerned about the state of the national economy and America's relationship with other nations, and they are likely to fly to Washington to confer with government officials. While they undoubtedly influence the government, they do not control it -- as some tycoons in the Gilded Age believed they did. 

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.
