Obamacare is not just the exchange, folks. All types of health insurance have been reformed by the law. That is why you will soon be calling it The Affordable Care Act.
Only the idiot fringe believe that Obamacare is a success. The simple fact that your messiah has moved the employer mandate back, past the next election, has moved the insurance premium increases back past the next election, and actually negated the individual mandate, ought to give you pause that the shit is going to hit the fan at some point.
Employer covered insurance has increased for the simple reason that it is still cheaper to the individual than the exchanges and it ensures that people do not get their tax rebates robbed by government. People are acting to protect themselves from Obamacare while they still can.
