Dave Warsh has a nice blogsite on economics, and his latest is on health care spending.
Well worth the read. He nicely lays out the case that we get more than ample return on our investments in health care. And a fine dynamist closer "So who's to say with any confidence whether the right figure for health care is 20 percent or 25 percent or even 30 percent? These things do move around."
Oh, yeah, and a bonus for you economists, he gives a succinct evisceration of Baumol's "cost disease" thesis.
