I always prefer to have ALL costs displayed up front, so we know what the ACTUAL true cost is. Subsidies encourage the opposite. Our very expensive involvement in the middle east is partially motivated by our concerns about keeping oil prices relatively low. So you might add military costs, including 50 years of medical treatment at VA hospitals for injured veterans. to our gas bill. Of course, we don't see it at the pump but we pay it anyway.We might choose different vehicles and driving patterns if we actually had total costs reflected at the pump. Perhaps we will drop the tax on Brazilian ethanol which is made from different materials that don't impact the food supply.
