$20 Gas is good for you!

$20 a gal is good so says Christopher Steiner in his new book.

At $6 a gallon, Americans will embrace diesel engines. At $8, many airlines will shut down, leaving Southwest Airlines Co. and JetBlue Airways Corp. as the dominant domestic carriers.

At $10, car ownership rates will plummet. At $12, exurbs will start becoming ghost towns. At $14, Wal-Mart Stores Inc. will die; its business model is built on cheap oil.

At $18, Americans might get what Europeans have enjoyed for years: high-speed trains. And as the price creeps up to $20 a gallon, the U.S. may finally frame a comprehensive energy plan
