The US Government should not have the power to regulate Doctors, drugs, food, oil, imports, exports etc. It should not have the power to go to war without clear and present danger. It should not have the power to make the Oil business viable by stationing floating fortresses in the gulf at our expense.
For those of you who want to tell me that we need "People To Regulate" Doctors, Drugs and Food: ask yourself, "Is the head of Monsanto the person I want to regulate Food?", because that's what you have. To Regulate Transport Safety, you have a man who makes high-power X-Ray machines.
The problem is not money or lobbyists. The problem is that there is a reason for them to spend their money. Of course, there will be a small number of fundamental rights that will need to be safeguarded - but they will be small, clear and understandable by Citizens.
