I find the use of "lies" twice in the beginning of the essay a hilarious rhetorical device, it's cheap but funny. Just wondering if anyone noticed it? How about you mk or flagamuffin? R&R are fighting a guy with a way bigger megaphone and are pretty much guaranteed to lose pop culture wise against Krugman, which is really too bad. Maybe it's not too bad actually, the arguments that R&R bring to bear in their letter aren't really arguments at all, I'd be slapped down in a moment if I had tried arguing from authority rather than theory in the classroom. R&R haven't proven anything, they aren't providing a theoretical argument more compelling than the opposition (does low growth create big debts or do big debts create low growth, the causality probably goes both ways).
