Constitutional limits on spending?

[KevinTheOmnivore]

Okay, I'll bite.

I don't know that I oppose it. I haven't read too many opinions either for or against it, although I have heard it mentioned before. The problem I see with a spending cap, correct me if I'm wrong, is that we'd never be able to pay down the existing deficit with a cap. Secondly, what would the cap be? I tend to cringe when I see policy wonks trying to solve public problems with mathematical equations. I'd imagine any such amendment would require a "formula" entailed with the amendment. So what spending gets justified and what becomes expendable? Any discretionary spending? Who defines a "national emergency"??? Will there be a set criteria for that...?
