The CBO costed what the Democrats put in front of them to cost. Which just happened be be 10 years of revenues but 6 years of costs. Duh!
Ever heard of Forbes?
"In the wake of a landmark Supreme Court decision, President Obama’s signature policy achievement is safe, and the implementation of the Patient Protection and Affordable Care Act (“Obamacare”) will continue as planned. The U.S. economy is another story. Obamacare’s projected economic consequences were negative when the legislation passed in 2009, and they remain so today, increasing the likelihood that national economic growth will lag expectations, and budget crises at the national and state levels will persist.
The reason is simple: Obamacare increases government regulations, increases taxes, and increases spending, but it never addresses the central problems with the current health care system. That is, it neither improves health outcomes nor controls skyrocketing health care costs. At a time of trillion dollar federal deficits and state and local budgetary stress, the legislation burdens the federal and state governments (to the extent they choose to participate) with additional expenditures. According to the Congressional Budget Office, Obamacare will cost an additional $1.5 trillion through 2021, some of which may be financed by the states through higher Medicaid and other health programs. This $1.5 trillion is equivalent to an additional annual cost of $1,261 per U.S. household, or a diversion of 2.5% of the average household’s gross income."
