Person for person, health care in the U.S. costs about twice as much as it does in the rest of the developed world. In fact, if our $3 trillion health care sector were its own country, it would be the world's fifth-largest economy. If you have health insurance, you may think it doesn't matter because someone else is paying the bill. You'd be wrong. This country's exorbitant medical costs mean that we all pay too much for health insurance. Overpriced care also translates into fewer raises for American workers. And to top it off, we're not even getting the best care for our money.
