Now, add it all up, and the plan I'm proposing will cost around $900 billion over 10 years, less than we have spent on the Iraq and Afghanistan wars and less than the tax cuts for the wealthiest few Americans that Congress passed at the beginning of the previous administration. Now, most of these costs will be paid for with money already being spent, but spent badly, in the existing health care system. The plan will not add to our deficit. The middle class will realize greater security, not higher taxes. And if we are able to slow the growth of health care costs by just one-tenth of 1 percent each year--one-tenth of 1 percent--it will actually reduce the deficit by $4 trillion over the long term.
