The economic landscape -- particularly for the United States -- certainly looks different than it did 30 or 40 years ago.

Globalization, the internet, and the rise of a second major economic power in Asia are all developments that would look rather odd to someone in, say, 1973-74. The world in 2008 is one characterized by economic change -- one that may usher-in even more historic political change in the months ahead.

But there has been one constant between the two eras (overlooking cyclicality): the price of oil. It was high, in real terms, in 1973-74, and it's high now. And one thing economists like Glen Langan know regarding economic conditions when oil's price is high -- it simply makes the cost of moving things, the cost of doing pretty much everything, more expensive. Whether it's dropping the kids off at little league baseball or at soccer practice, or transporting a supply chain order of refrigerators across the country, a high oil price "simply increases the cost of motion," he said. And there are few positives for the U.S. economy. Further, it takes dollars that could create spin-off economic effects -- disposable income that could be spent somewhere else -- and simply removes them from the economy.
