Mike Jackson is absolutely correct that the gasoline tax should be increased. Essentially, all the effects of such a tax would be beneficial -- less road congestion, less pollution, lower federal budget deficit, lower trade deficit and less room for OPEC to raise prices.
With gasoline sufficiently expensive, demand would shift to fuel-efficient vehicles, and those troublesome CAFE standards would become irrelevant.
So why doesn't it happen? Because our senators and representatives know they won't be re-elected if they vote to raise the gasoline tax.
The best hope is for a revenue-neutral approach -- as Jackson suggests through an energy tax credit. Another possibility would be to use the extra revenue to provide liability insurance coverage for all drivers. That would also solve the problem of uninsured and underinsured motorists.
