THE PERILS OF READING WHEN TIRED. Yesterday, I wrote that Arnold Kling's book failed to define the terms "very poor" and "very sick." Today, he writes that "In the simulation of my proposals in the chapter on matching funding to needs, I define poor as below the poverty line and I define very sick as having annual expenses over $5000 for the non-elderly and over $20,000 for the elderly. " He's right -- I'd missed it on my first read-through. Mea culpa.
