Just before Democrats passed the ObamaCare bill, they frequently claimed that it would "bend the cost curve"--that is, to change the curve that had been steeply upwardly sloping (over time) to one that is downward sloping, or at least less steeply upwardly sloping.
That's why this graph, published yesterday in the New York Times, is especially remarkable. It shows how the change in health care costs (but not the actual level of costs) had actually been sloping downward since 2002 or 2003. But between 2010 and 2011 it takes a dramatic turn upwards. It's about the most hockey-stick-looking graph I've ever seen in social science.
Peter Orzag, President Obama's OMB chairman at the time that ObamaCare was considered, was perhaps the most vociferous about claiming that the bill would "bend the cost curve." Esquire magazine published this in-depth interview, which discusses those claims. The interview was part of a series of articles about the "Best and Brightest" people of 2009.
