So John is worried about global warming, and he figures that one thing that we should do about it is eliminate the interest deduction for houses over 3000 square feet. Is it really possiblethat a guy in his position really doesn't understand the effect this would have on the economy? That prices for houses over 3000 sf would completely collapse? And prices for houses under 3000 sf would skyrocket, thus putting home purchase out of reach of more lower income Americans? That it would essentially destroy the economy? Hello? How can liberals be this dense about economics? I mean, I understand that they aren't intelligent enough to understand that lowering tax rates raises tax revenue; it's counterintuitive and you have to know something, which few of them do. But this, this is so mindbogglingly stupid that I can't even comprehend it. http://www.washingtonpost.com/wp-dyn/content/article/2007/08/24/AR2007082400897_pf.html?
