Hey, I've got an idea. How about in this next election cycle, we kick everyone out of office everywhere, and put in nothing but brand new people. Sure, they may not know the ropes, and yes they might not act as a cohesive whole, but at least it won't be such an easy job for the business world to control all of them. And maybe, just maybe, if they don't go passing as many new laws, we won't have as many bad laws and future battles to fight.
First off, let me say that I like your writing. Most of us here(including me!) don't usually bother with well structured arguments. Well done
However, with that part of your post^^^, I have some issues. I don't know what state you live in, but in California, all Assembly members and State Senators have term limits. I believe they are currently two terms each (equal to four years for Assembly members and I think eight years for senators). This sounds good right? New blood is guaranteed every few years right? Wrong. What ends up happening is political aids and lobbyists (there's that word again

) end up "helping" the newely elected senators and assemblymen. In essence, the office is on a continual rotation, with the only constant being the root cause of the problem. In truth, the more experience a politician has, the less likely they are to lose sight of the more important long-term goals of a government.
For example, LBJ was a career politician. His strength was in parliamentary politics. His ability to control both the House and the Senate within a matter of years was amazing. Now contrast this with the fairly young and inexperienced JFK. Sure JFK looked good on TV, but in reality, he was a poor leader. Most of his ambitions were blocked by his own party in the House and Senate. Only LBJ's relationships with powerful senators and House leaders allowed some legislation to go through. History shows us that in the end, after more than two years, JFK hadn't been able to pass any meaningful legislation. Contrast this with LBJ, who after only two years, was able to craft and pass landmark legislation, including the Civil Rights Act, Medicare, and Medicaid. Johnson's experience was what allowed him to do all this.
Now, if we were to kick out all the people we could in 2008, which would include 435 House members and leaders, the President (duh), and 33 Senators, and even if we were able to stop all lobbying, donations by corporations (and consequently individuals as well), we would have an entrenched Senate. With a 67 vote majority, there would be endless pigeon holding, filibustering, and "Nay" votes on the floor. No president would be able to sign a law which dies on the Senate floor, and our situation might end up being worse because there would be a fear to act. Not to mention the fact that the newely elected House members and leaders (remember, 435 of them) would have to learn procedure before they would be effective as leaders.
So I guess it comes down to the fact that the only people who are strong enough to stand politics are the very people we have elected right now (or those we will elect in a year and two months).
I think a much better solution would be to demand more out of our reps. There's nothing wrong with making them disclose who they speak with, who they associate with, and from whom they've recieved money. If we want a better government, it's up to us to demand one.
