Keep in mind that every state has strict term limits. Approximately 0 of them are significantly better run the the Feds. The problem with our democracy isn't the faces we're sending to Washington. It's the people who vote for those faces. And yes, I just said that most of the problems the American people have with American democracy are the fault of the American people.
We don't agree on jack-squat. Paul Ryan strongly believes that one of the biggest problems facing the nation today is that it is over-taxed, particularly on the wealthy. If you cut their taxes and allow them to create jobs everyone will be better off. Barack Obama believes the opposite. Therefore for them to agree on a budget (which includes taxes), they basically have to base it entirely on the last year's budget (aka: the one everyone hates), because otherwise one of them would be admitting defeat.
And the whole goddamn time they have snipe at each-other in a ridiculous attempt to gain some trivial advantage in negotiations our grandchildren will not give a fuck about. Seriously. A couple years back Bush's tax cuts expired, and there was a massive government shutdown because Obama wanted them to expire for like 99.8% of Americans, but for taxes to go up on the others; but Paul Ryan wanted to keep them around for every-damn-body. As a Democrat I loved that Obama stood up for his principles, because they are my principles, but even I am objective enough to acknowledge it was a fucking stupid fight to have.
The only ways to reduce the BS would be mass-murder of roughly 10 million of the voters from one side or the other, or centralize power more so that the guy who came in second didn't have veto-power over public policy.
