For example, it is insanity to suggest that the thing over which your are negotiating is in fact your concession. How would that work in the real world? You go into a car dealership and offer the salesman the wholesale price and he offers you the sticker price. You come up a little on your offer and he comes back with the sticker price again. You say, "WTF? You've got to negotiate!" He says, "I've already conceded that you can have the car for full retail! What do you want from me, blood?!"
Never mind the fact that it would have been pure insanity not to raise the debt limit. Never mind the fact that it was absurd from the outset to hold the country hostage over something that any sane person knew had to be done. Forget the fact that Congress has raised the debt limit over 100 times in the past without insisting on this lunatic game of chicken.
Let's look at what actually happened.
Democrats wanted substantial deficit reduction with a significant portion coming from revenue enhancement, albeit with the majority still coming from spending cuts.
Republicans said no, we will take less deficit reduction but we will never agree to anything that could remotely be described as a tax increase.
Democrats said, okay, we'll offer significant deficit reduction, and we'll shift the balance so that the vast majority of it comes from spending cuts.
Republicans said no, we will not accept anything remotely like a tax increase no matter what. We're crazy. We'll blow this place up!!
AND ... AAAND we will only agree not to blow up the economy if you give us a balanced budget amendment that would surely blow up the economy anyway if it could miraculously get through the amendment process!
Democrats said, holy sh*t, they really may be crazy. Okay, we'll offer you somewhat less deficit reduction and NO tax increase or anything that could in any way be interpretted as a tax increase.
Republicans said ... NO!! We will ONLY accept EVERYTHING we asked for IF you agree to do this whole economy-shaking dance again in six or nine months!
You are delusional if you think the republicans were negotiating in good faith.
