When asked if Obamacare responsible for the slowing down of healthcare cost in America, Avik Roy a senior fellow at the Manhattan Institute stated, "No. First of all, the law hasn't really been implemented. It’s just starting to be implemented. The CMS report from the Obama Administration specifically said that the affordable care act had minimal effect on national health expenditures."
Roy credits the slowing down of healthcare cost in American to President Bush's medicare perception drug reform.
