Iowa lawmakers are struggling over what to do about proposals to raise the state's per-gallon fuel tax. Iowa has had a 21-cent per-gallon tax in place since 1989. Lawmakers are considering upping it to 29 or 31 cents per gallon. Doing so doesn't seem unreasonable to us. The money collected pays for roads, used by drivers, who pay the tax. So the tax is essentially a user fee, and that's always a preferable way for government to fund services.
