I remember seeing somewhere that Dr. Paul supports raising corporate taxes (after eliminating personal income taxes, of course). I also read a convincing argument about how corporate taxes are authorized under the Constitution while a national sales tax, which I would prefer, is not. Putting Constitutional arguments aside, I'm interested about what people think about corporate taxes. After reading the FairTax book, it seems apparent to me that businesses waste so much money preparing taxes and making decisions in relation to taxes, and other countries seem to get a competitive advantage because of that. However, corporate taxes are quite helpful in controlling negative externalities (spillover costs in production, for example a factory that pollutes a city's water supply, thus forcing part of the burden onto individual citizens. Corporate taxes would shift that burden back to the business so that it would pollute less). Personally, I would like to get rid of most corporate taxes, but have some left to deal with situations like the one above.
