“The ACA health insurance subsidies are the most significant expansion of entitlements since the 1960s. In light of the precarious fiscal outlook for the federal government, its cost is a central concern to policymakers and taxpayers alike. When the ACA passed in June 2010, the Congressional Budget Office projected the budget cost between fiscal 2012 and fiscal 2019 to be $462 billion. By June 2012, the cost for these same years had jumped to $574 billion, an increase of nearly 25 percent.”
