More than that, it would shift the burden of transportation infrastructure costs away from the taxpayers in general and onto those who use the roads and bridges the most and consume the most gas. It would be a much more fair way to fund the federal portion of the bill for building and maintaining our basic infrastructure. To make this work the money from the higher gas tax ought to be locked into funding transportation and nothing else. There should be no possibility that it would be 'repurposed'. Keep it out of the grubby hands of the porkmesiters. The DoT could essentially function independently, with some Congressional review. Make it entirely self-funded by the gas tax, working directly for the people, paid by the people and answerable to the people. That's the way government ought to be done.
I'm with the NTU on reducing and eliminating taxes and cutting the government down to the bare bones. But the gas tax has the potential to be one of the most legitimate forms of taxation with the money being applied to one of the few genuinely necessary functions of government. While we should oppose the pork, it's a distraction from the main point. We shouldn't be against raising the gas tax just because it's a tax. There's an opportunity here to completely rethink how we fund government, and we shouldn't miss it because our vision is just limited to cutting taxes.
