Today I'm thinking the fundamental policy difference among us may be our respective judgments about the problem: Is it big problem, a medium sized problem, or a little one?  Depending on how we see that, we may conclude we need dramatic, transformative action, little policy tweaks, or no government response at all.  As I hope prior posts make clear, especially the last one, I think we are much closer to (a) than to (b).  What do you think?
