Well, the final poll results are in and reflect the general split all along: A small majority prefer not to introduce a sales tax. I suspect that it has mostly to do with concerns of regressivity and the distrust of politicians to do enough to counter it. I concede that it would be a tough political fight, but I am also quite concerned about being such an outlier on income taxes. Still my support for the sales tax waned the more I got into the morass of the data. I would support a tax package that introduced the sales tax and reduced the income tax but also made it progressive. I think, however, the ability to deduct the income tax on federal returns is a pretty big counterargument, so I would not mind a relatively high income tax along with a small sales tax.
But my readers have spoken and I am beholden to them. I have tried my best to educate (while still keeping my job - meaning having to do the tax research in my spare time) and after delivering what I hope is a fair reading of the evidence and arguments, my readers have filed to find convincing the arguments for the tax. Thus I consider the case closed. If readers of The Oregon Economics Blog don't think it is good for Oregon, than it is not.
Thanks to all who participated in the poll.
