Politicians trying to pretend that this is either the best way to reduce climate change or the best way to fund roads are pathetic. Taxes on consumption are going to do much better at reinforcing poverty than at reducing climate change. What needs to be done is a nationalization of non-renewable energies so that they can be quickly phased out. In the meantime, prices need to kept at a reasonable rate. A cap on carbon emissions and a carbon tax is where the taxation of pollution needs to be focused on. I realize that a gas tax has a purpose of discouraging driving too much to reduce carbon emissions, but what is a lower-income person who must commute to work supposed to do in this situation? Unless we have a nationwide free public transit system, the gas tax will continue to negatively affect the poor.
Of course, the oil industry would assassinate someone before they let this happen.
