Business, labor, and other interests act more formally through the rule making process as well, particularly when a proposed rule or regulation is open to public comment. Although anyone may provide comments to administrative agencies, in reality most comments come from the interest groups that are directly affected by the agency's policy. So, if the FAA wants to require that all children under the age of two be seated in a child safety seat on airplanes, one would expect the airlines, and perhaps groups representing consumers, to provide a majority of the public comment.
