As for the matter of representation, if no one is arguing for your point of view, how can you say that you are represented? Also, I think the idea of representation by geographic division is stupid. Candidates should be voted on by ideas. I may be in the minority in any given locale, but I am still part of a rather large group. Everyone should vote for the people they want to represent them, regardless of where you live, and those people should get votes based on how large their constituency is. Pipe dream? Yup. Still would be a heck of a lot fairer.
There is a reason we have an electoral college. Our founding fathers were fairly wise. The popular vote is great in theory but piss poor in reality. The politicians, lobbyist, and special interests would concentrate on those areas which have a very large population. I will say, there is a day in the future where the population dynamics in this country will make a popular vote viable in terms of fairness.
If you are truly concerned with the "fairness" of your representation, you should be advocating for a multiparty system. Very few people are hook, line, and sinker for either of our two parties. A multiparty system would promote a diversity of ideas and angles to address the various problems which face the county. They will also allow for people to be more accurately represented both by a representative and a party platform.
At the end of the day, we all have an equal say in our government. That is as fair of a system as you can devise for a society. If you believe your representative is too vanilla for your tastes (either way), then advocating for a more fractured political system is the way to go.
As to Social Contract Theory: There is a necessary amount of sublimation of the individual's will that is required within any society. However, the amount necessary is not that hard to determine and anything that exceeds that amount is criminal, even if it is not illegal. My authority to exercise my will ends when it becomes an attack on you. Like the old idea: 'your right to swing your fist ends at my nose.' Society has a right to govern itself, but only to prevent the initiation of force, theft, coercion, and fraud. That means that any government program or law that goes beyond that is not legitimate. To take from me (tax) and use it to fund illegitimate programs is a form of theft, because illegitimate taking is theft.
Sour grapes. You wish to live within a better social contract. Congrats. You are one of three hundred million other people in the United States who would also want to tweak the current social contract more to their liking.
I actually agree with all of your outlined grievances. However, we are only two individuals living within a society. It is a
social contract. If our fellow countrymen had our ideals, our social contract would reflect those ideals. They don't. Unfortunately, they are the majority at the moment. As I responded to fallguy, I do believe we are on the verge of the s*** hitting the fan. I am not sure if it will be next year, five years, or ten years down the road but it is coming. I believe the both political and economic paradigm shift which will result in a new social contract closer to what you and I desire.
To your last point, again, sour grapes. Those laws are legitimate. They were enacted by a Congress which was elected in a fair manner by the people, signed into law by a President who was also elected by the people, and upheld by the Judicial Branch as outlined by our Constitution. Although you or I might disagree with them fundamentally, they do reflect the overall will of the people. I do not understand why you can't except that you and I are in the minority on a lot of issues. It does not follow that because we disagree with the tax and spending policies of our democratically elected government; that those laws then constitute "theft."
