A CHALLENGE TO A BET: From economist Don Boudreaux to ObamaCare mavens Peter Orszag and Nancy-Ann DeParle: “Pick any year in the future between 2021 and 2046. Tell me your estimate today of how much Uncle Sam will spend on health care that year. I’ll bet each of you $5,000 that Uncle Sam’s actual expenditures on health care in that year — adjusted for inflation — will be at least 25 percent higher than your estimate.” They might as well take the bet. By then, $5K will probably buy a Big Mac.
