Charles Krauthammer, in January of '07:
First, tax gas. The president ostentatiously rolled out his 20-in-10 plan: reducing gasoline consumption by 20 percent in 10 years. This with Rube Goldberg regulation — fuel-efficiency standards, artificially mandated levels of "renewable and alternative fuels in 2017'' and various bribes (er, incentives) for government-favored technologies — of the kind we have been trying for three decades.
Good grief. I can give you a 20-in-2: tax gas to $4 a gallon. With oil prices having fallen to $55 a barrel, now is the time. The effect of a gas-tax hike will be seen in less than two years, and you don't even have to go back to the 1970s and the subsequent radical reduction in consumption to see how. Just look at last summer. Gas prices spike to $3 — with the premium going to Vladimir Putin, Hugo Chavez and assorted sheiks, rather than the U.S. treasury — and, presto, SUV sales plunge, the Prius is cool and car ads once again begin featuring miles per gallon ratings.
Thomas Friedman, today:
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.
Again, no comment from me.
