You're absolutely right.
But I was just being facetious about trading spending cuts for tax hikes, at least as a debt ceiling negotiating tactic. (It might make sense in more normal times, with a more responsible Republican party.)
The GOP has already shown itself willing to risk nuclear war, environmental disaster, or global economic collapse rather than pay their fair share of taxes. So we could offer it as a political gambit without the slightest chance they'd agree to it. The Right has shown themselves to be masters of dirty pool, lets see how good they are at poker.
