James Pethokoukis puts forward some much-needed heresies (to the right) on economic policy: "No to the Flat Tax and Other Stale Ideas." It's a good sign this is getting published at National Review Online. Less encouraging (though not unexpected) are the comments, the overall gist of which is that these orthodoxies must never be reconsidered and who is this "kid" to do so anyway? (I don't know how old Pethokoukis is, but if he was at US News in 1997, he's not all that young, and it's a dumb "counterargument" anyway.)
UPDATE: Also see Ramesh Ponnuru's "Reaganism After Reagan," found via Justin Green, who points out that it's "obvious but needs to be said."
