The United States House and Senate has been over run by Corporate lobbyist that line the pockets of our representatives for far to long. They are creating and influencing laws and regulations that suite their own bottom line, shut down their competition, and are not in the best interest of the consumer or the American People. This creates an atmosphere of Corporate Oligarchy with in the United States, and is effectively ruining our free market system of capitalism. Legislation should be passed banning "For Profit" Corporate lobbyist from the halls of congress, but allowing "not for profit" constitutional rights special interest groups to continue challenging and/or influencing new legislation. Examples of "For Profit" Lobbyist are; The Tobacco Industry, Large Pharmaceutical, Monsanto, ect.
