The Patient Protection and Affordable Care Act, better known as Obamacare, has been controversial ever since it became law. A recent report from the Congressional Budget Office recently concluded that Obamacare could cause full-time employment to drop by 2 million.

As a result, it could hasten the end of surpluses in the Social Security Trust Fund.
