Lawrence Lessig, a professor at Harvard Law School and author of Republic, Lost, suggested that the moneyed persuasive power of special interests has insinuated itself between the people and the lawmakers. He quoted congressperson Jim Cooper who remarked that Congress had become a "Farm League for K Street" in the sense that congresspersons were focused on lucrative lobbying careers after Congress rather than on serving the public interest while in office. In a speech, Lessig suggested the structure of incentives was such that legislators were tempted to propose unnecessary regulations as a way to further lobbying industry activity. According to one view, major legislation such as proposed Wall Street reforms have spurred demand for "participating in the regulatory process." Lessig suggested the possibility that it was not corporations deciding to take up lobbying, but Congress choosing to debate less-than-important issues to bring well-heeled corporations into the political fray as lobbyists. As a result of his concerns, Lessig has called on state governments to summon a Second Constitutional Convention to propose substantive reform. Lessig believes that a constitutional amendment should be written to limit political contributions from non-citizens, including corporations, anonymous organizations, and foreign nationals.
Why has there been so much resistance from the government to enact a law to limit political contributions from donors in the U.S.? I remember a lot of discussions were had, but nothing was ever done to limit contributions from donors. What are the barriers and the incentives that prevent the government from taking any significant actions in this regard?
