The other thing is that even though the debt doesn't matter in the way most people think it does, that doesn't mean you can throw monetary favors and dollars around to everyone inefficiently. We have a duty to spend where it is beneficial and cut back where it is not. It is absolutely not beneficial to keep what was always supposed to be a temporary cut to those who are well off and aren't going to affect demand in a giant way. We can use our money supply in a far more beneficial and efficient way.
And lastly, even though the above is true, people do think the debt matters, and that's what the American people feel at this moment. And so, if we are going to cut our spending, then we should least of all do it to that which will affect demand right at this moment. We should do it on that which will not affect demand, and those making that much money statistically won't affect demand in such a way that will harm the economy.
