Our Transportation Infrastructure is Crumbling

In President Obama’s State of the Union address last January, he referred to the problem of our crumbling transportation infrastructure.

One solution is at the gas pump. When you filled your tank, you paid for fuel and probably also a road. In 1956, the first interstate highway system was financed with a 3-cent a gallon fuel tax. Now the federal tax is 18.4 cents for gasoline. Add that to your state’s tax and the total could be as high as 67 cents a gallon if you live in New York or California. (For state gas taxes, please see below.)

Still though, because gas taxes just don’t raise enough money, the federal Highway Trust Fund might soon be broke. Do you think the gas tax should go up? Or would you support being taxed by the mile with your GPS providing the data? Or, should we add more tolls and use EZ pass everywhere?

Before you decide, please consider your tax philosophy. Yes, you could say that a tax at the pump is fair because we all pay the same amount for the same purchase. Or, you could say you approve of the gas tax being used on roads because it means that the people who use the roads are paying for them.

However, do you feel okay about regressive taxation? With regressive taxes like the gas tax, people who earn less pay a higher proportion of their incomes. (A $10 tax on someone who earns $100 is 10%; a $10 tax on someone who earns $1000 is 1%.)

And finally, Harvard economist Ed Glaeser said that 4 words summarize 40 years of transportation research at Harvard: “Bus Good; Train Bad.”

Sources and Resources: While a good WSJ article on gasoline taxes was the source of most of my gas tax facts, I do recommend this Bloomberg article by Ed Glaeser and this Hamilton Project paper on infrastructure spending. Also, here, EconLife looks further at highway spending and the Highway Trust Fund.

Told that someone earns $250,000 a year, you should ask, “Where do you live?”

According to CNN, you would need to earn $545,000 in Manhattan to spend what $250,000 will buy in Missoula, Montana. On this map, you can see how your cost of living compares to the national average.

Specifically, here is a shopping list: “ground beef, tuna, milk, eggs, margarine, potatoes, bananas, bread, orange juice, coffee, sugar and cereal.” In Manhattan: $40.29; In Twin Falls, Idaho: $23.41.

Buying a 3-4 bedroom house? $750,000 in Glendale, California; $375,000 in Twin Falls, Idaho.

You can see where this is going. At first, it sounds simple. President Obama suggested $250,000 as a dividing line for increasing taxes. One number, one level of income. But is it?

The Economic Lesson

Taxes can relate to income in 3 basic ways:

  • Progressive taxation takes a higher percent from those who have higher incomes. 
  • Regressive taxation takes a higher percent from those with lower incomes. 
  • Proportional taxation takes the same percent from all.

Our current income tax approach is progressive while a sales tax is regressive.

An Economic Question: Using data from this map, explain how the cost of living varies.

Some people believe that government spends more when it has an affluent population to pay for it.  In a recent NY Times column, David Leonhardt presents a slightly different perspective. Instead, he says that because we are a more affluent society, we want government to spend more. As he expresses it, “A tax increase is…a result of a society becoming richer.” As economic growth accelerates, so too does what people want from government.  We want additional services; we want a transport infrastructure; we want medical care.  

So far, how have we funded these wants?

  • On the revenue side, federal taxes have totaled close to 18% of GDP.
  • The individual income tax is our largest source of revenue.
  • The second largest source is social insurance taxes (social security and Medicare) while corporate taxes are a distant third. 
  • During the 1950s and 1960s, the top marginal tax rate was actually 91%.

Where do we go from here? More tomorrow…

The Economic Lesson

There are three basic tax approaches: 1) Progressive taxation: the affluent pay a higher percent of their income than those who have less. 2) Regressive taxation: those who have less pay a higher percent of their income than those who have more. 3) Proportional taxation: everyone pays the same percent of their income. Our individual income tax system is progressive, sales taxes are regressive, and the Medicare tax is an example of a proportional tax.
