You are correct that I made an error in my calculation, but my point still largely stands.<p>I took the parent at face value for the claim that 50% of roads are funded by use fees. That means the other 50% are paid for with general income taxes. Nearly all income taxes are paid for by the top half of earners. If we assume that everyone drives about the same amount, then the bottom half of the country gets the full value and use of roads while only paying for 25% of the total cost.<p>I bring this up because the parents point seemed to be that road subsidies are an implicit subsidy to oil companies. But people need to get around somehow, and the current way of funding roads should be perfectly compatible to conventional morality.<p>At the same time, I oppose all subsidies and can only imagine the amazing methods of transport that would exist if the government did not actively interfere and manage this market.
