By THOMAS L. FRIEDMANImagine for a minute, just a minute, that someone running for president was able to actually tell the truth, the real truth, to the American people about what would be the best — I mean really the best — energy policy for the long-term economic health and security of our country. I realize this is a fantasy, but play along with me for a minute. What would this mythical, totally imaginary, truth-telling candidate say?
No, our mythical candidate would say the long-term answer is to go exactly the other way: guarantee people a high price of gasoline — forever.
This candidate would note that $4-a-gallon gasoline is really starting to impact driving behavior and buying behavior in way that $3-a-gallon gas did not. The first time we got such a strong price signal, after the 1973 oil shock, we responded as a country by demanding and producing more fuel-efficient cars. But as soon as oil prices started falling in the late 1980s and early 1990s, we let Detroit get us readdicted to gas guzzlers, and the price steadily crept back up to where it is today.
We must not make that mistake again. Therefore, what our mythical candidate would be proposing, argues the energy economist Philip Verleger Jr., is a “price floor” for gasoline: $4 a gallon for regular unleaded, which is still half the going rate in Europe today. Washington would declare that it would never let the price fall below that level. If it does, it would increase the federal gasoline tax on a monthly basis to make up the difference between the pump price and the market price.
To ease the burden on the less well-off, “anyone earning under $80,000 a year would be compensated with a reduction in the payroll taxes,” said Verleger. Or, he suggested, the government could use the gasoline tax to buy back gas guzzlers from the public and “crush them.”
But the message going forward to every car buyer and carmaker would be this: The price of gasoline is never going back down. Therefore, if you buy a big gas guzzler today, you are locking yourself into perpetually high gasoline bills. You are buying a pig that will eat you out of house and home. At the same time, if you, a manufacturer, continue building fleets of nonhybrid gas guzzlers, you are condemning yourself, your employees and shareholders to oblivion.
What a cruel thing for a candidate to say? I disagree. Every decade we look back and say: “If only we had done the right thing then, we would be in a different position today.”
But no politician dared to do so. When gasoline was $2 a gallon, the government never would have imposed a $2 tax. Now that it is $4 a gallon, the government should at least keep it there, since it is really having the right effect.
I was visiting my local Toyota dealer in Bethesda, Md., last week to trade in one hybrid car for another. There is now a two-month wait to buy a Prius, which gets close to 50 miles per gallon. The dealer told me I was lucky. My hybrid was going up in value every day, so I didn’t have to worry about waiting a while for my new car. But if it were not a hybrid, he said, he would deduct each day $200 from the trade-in price for every $1-a-barrel increase in the OPEC price of crude oil. When I saw the rows and rows of unsold S.U.V.’s parked in his lot, I understood why.
We need to make a structural shift in our energy economy. Ultimately, we need to move our entire fleet to plug-in electric cars. The only way to get from here to there is to start now with a price 
signal that will force the change.
Barack Obama had the courage to tell voters that the McCain-Clinton summer gas-giveaway plan was a fraud. Wouldn’t it be amazing if he took the next step and put the right plan before the American people? Wouldn’t that just be amazing?
