Bartlett's new book is fantastic. I think it just came out yesterday, but I bought it and read it last night. I think he's pretty correct about Supply-Side becoming a religion. The dogmatic beliefs that taxes can NEVER be raised, that revenue increases from all tax cuts, etc is absurd, but like quasi-religious Keynesianism 50 years ago, the true believers will never accept evidence that they're wrong. Kudos to Bartlett for saying speaking some very important truths.
