Writing in The New Yorker, Elizabeth Kolbert illustrates the power of analogy:
A man walks into a bar. He orders several rounds, downs them, and staggers out. The man has got plastered, the bar owner has got the man’s money, and the public will get stuck with the tab for the cops who have to fish the man out of the gutter.
The man pulls into a gas pump. He sticks his BP or Sunoco card into the slot, fills up and drives off. He’s got a full tank; the gas station and the oil company share in the profits. Meanwhile, the carbon that spills out of his tailpipe lingers in the atmosphere, trapping heat and contributing to higher sea levels. As the oceans rise, coastal roads erode, beachfront homes wash away, and, finally, major cities flood. Once again, it’s the public at large that gets left with the bill.
In both cases, Kolbert endorses the “fair and logical” solution: The man should be taxed to incorporate the costs that his choices impose on the rest of society.
I like this game. Can I play too?
A man chooses to build his house on the oceanfront instead of 100 miles inland. This makes him especially vulnerable to rising sea levels and therefore leads him to lobby for a carbon tax. The man gets his house; the builders and contractors share in the profits, and the public at large bears the consequence of higher gas prices.
Some people want to burn a lot of carbon, which raises global temperatures, imposing costs on owners of oceanfront property. Other people want to protect their oceanfront property, imposing costs on the people who want to burn a lot of carbon. A journalist at the New Yorker convinces her readers that the only “fair and logical” solution to this conflict of interests is to come down entirely on the side of the property owners, leading to the implementation of suboptimal policies. The journalist gets paid, the magazine editors congratulate themselves on the influence of their writers, and the general public suffers the consequences.
Should the property owner and the journalist be taxed for exerting their malign influences?
