From Tim O'Reilly:

Driving home from work, listening to NPR's story about health care costs, I couldn't help but be struck by a couple of numbers. The Obama health plan will cost a trillion dollars we're told. A TRILLION sounds big enough to end the debate, doesn't it?

Then I hear, almost as a footnote, that that trillion is over ten years. That's still a big number to be sure. A hundred billion dollars a year. But then later in the story, I hear that US total health care costs are $2.2 trillion a year. Suddenly, that $100 billion a year doesn't sound so big. That's only a 4.5% increase.
