That's twice as much as any other country in the world spends. And American health, as measured by life expectancy and infant mortality, is not a good as about 10 other countries. In short, for spending twice as much, we don't get any healthier.
So Congressional attempts to cut the expense of Obamacare are the right thing to do. We ought to cut healthcare spending down to 10% of GNP, from 19% today. Every other country in the world offers health as good as in the US, and spends only 10% of GNP doing it. It they can do it, so can we.
