THIS IS NOT AN EXPLANATION

(h/t Steve Benen)

Here's an excerpt from an interview Rep. Paul Ryan had with NPR:

NPR: As you look forward, if you’re going to reach an agreement with the Democrats that raises debt ceilings, avoids calamity, is there ultimately some room that you can imagine, for — from your standpoint — at least some nominal tax increase that gives the possibility for both sides to walk into a room and come out of a room and say, we got some of what we wanted here? Or is that absolutely…

RYAN: I don’t, yeah, I don’t see it. And let me explain why, and this isn’t a political thing. It’s an economic belief. It’s an economic doctrine thing.

I don't want to get too deep into parsing but it seems that Ryan is asserting that supply-side economics CANNOT be wrong and CANNOT be compromised.  Ryan's past statements about his admiration for Ayn Rand backs up this assertion.
