Whatever form it takes, health care reform will increase the number of Americans covered by health insurance. But there is concern that the legislation will not bend the cost curve—that is, will not reduce the growth of health care costs so that it more closely resembles the growth of the US gross domestic product (GDP). Currently, health care consumes about 16% of the GDP; advocates of bending the cost curve hope that in 2020 it will still consume roughly the same proportion.
