Describe the role that special-interest groups play in U. S. democracy. Use details to support your answer

An interest group is an organization whose members share common concerns, and try to influence government policies that impact those concerns.

Elected officials frequently complain about the influence of "special interests" on American politics. The fact is, however, that interest groups work closely with members of Congress and the administration to draft legislation and policy initiatives, provide information both to government and the public on a broad range of topical issues, and contribute significantly to political campaigns. The number of interest groups has grown dramatically in recent years, and it is difficult to think of a segment of American society that is not represented by one.

Interest groups can be classified as to the groups that they represent. Examples of economic interest groups include the following:

Big business (National Association of Manufacturers)

Big unions (AFL-CIO)

Trade associations concerned with a particular industry or segment of the economy (American Petroleum Institute)

Organizations of professionals (American Medical Association)

The goal of these groups is to protect the economic well-being of their clients or members. The AMA, for instance, long opposed Medicare and the development of health maintenance organizations (HMOs) as "socialized medicine" in favor of traditional fee-for-service.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
