A survey of 4,562 plan purchasers by McKinsey & Co found that 11 percent had no insurance and 89% were switching from an existing plan (presumably due to being eligible for a subsidy) or were replacing a plan that had been canceled due to ObamaCare: Health Exchanges See Little Progress on Uninsured – WSJ.com. Another source suggest 2/3ds were already insured. It’s likely between 65% to 90% were already insured.
What this means: The #1 goal of the Affordable Care Act was to lower prices charged for medical care; that part already failed. The #2 goal was to provide insurance access for the uninsured; that part is failing so far. The part that has worked so far is a dramatic expansion of Medicaid. If that is all that happens, this could have been done with out forcing the massively frustrating, time wasting and expensive changes on the market place.
