The Highway Trust Fund will be out of money in a few months, mainly because Congress insists on spending more than it takes in. To avert this supposed crisis, Republican leaders are proposing to cut Saturday deliveries of mail and use the savings to replenish the trust fund.
There’s actually a tiny grain of Constitutional sense behind this proposal. The original legal justification for federal involvement in highways, back when members of Congress actually cared about such things, was that the Constitution authorizes Congress “to establish Post Offices and post Roads.” If the “post roads” aren’t paying for themselves, then who better to pay for them than the post offices?
In this sense, the Republican proposal is slightly more rational than President Obama’s proposal to use the increased revenues from a corporate income tax reform that will eliminate loopholes but reduce corporate tax rates. The administration predicts reducing rates will reduce corporate tax obligations in the long run but closing loopholes will increase revenues in the short run (interesting how Obama is promising corporations lower taxes after he is out of office in exchange for higher taxes when he is still in office). Obama wants to use some of those increased revenues to supplement the Highway Trust Fund.
More than offsetting the tiny Constitutional sense of the Republican proposal is that it will take ten years of Postal Service cuts in order to cover one year’s worth of red ink from the Highway Trust Fund. In other words, the plan is far from sustainable and will simply lead to another transportation cliff in a year or so.
