Americans want high-speed rail, as long as someone else pays for it. States are chuffed upset, for example, because the federal government now says it wants the states to put up 20 percent of the capital cost. The original Federal Railroad Administration grant guidelines issued back in 2008 suggested that the feds might pay all of the costs. Though they added that states that provided matching funds might be more likely to get federal grants, no doubt some states feel betrayed by this change of policy.
Someone is going to say, “but the federal government paid 90 percent of the cost of interstate freeways, so why will it only pay 80 percent of the cost of rail?” The crucial difference is that both the federal and the state shares of the interstates were paid out of gas taxes, in other words, user fees. (Though called a “tax,” the gas tax was a user fee because it was imposed only on purchasers of gasoline–98 percent of which was used for driving–and because state gas taxes from the start, and federal gas taxes after 1956, were dedicated to highways.)
The interstates were also built on a pay-as-you-go basis: no borrowing in anticipation of future federal gas tax revenues. This introduced feedback into the system: if people didn’t drive, there was no money to build roads. That’s why it took longer than expected to complete the systems: not because people didn’t drive on the interstates–they drove on them like crazy–but because neither Congress nor the states indexed gas taxes to inflation.
