It doesn't get any clearer than this, yet to some, it still won't matter. They'll still claim Obamacare had nothing to do with Big Insurance sending out cancellation notices:
The cancellations come as a result of the 2010 Patient Protection and Affordable Care Act, which says that health insurance policies that fail to offer added benefits, such as prescription drug coverage and free preventive care, can’t be sold after this year even if they’re cheaper. With the online site expected to face difficulties through November, Americans may have only weeks to find replacement coverage, and many may end up paying higher premiums.
Something else that is getting lost in this initial shuffle is the employer-paid health plans. The Administration is trying to downplay the effect of Obamacare cancellation notices, by reminding us that around 80% of people are covered by employer plans, or Government programs, and thus not affected by the mandate. What they neglect to mention (and what I think will be the true tsunami of Obamacare) is when smaller to medium sized companies realize that it is cheaper to give their employees a stipend (like a car allowance, or cell phone allowance) to be used toward the employee buying their own coverage on the exchanges, than it is to pay for employer provided coverage.
If that happens before Obamacare gets a large pool of young, healthy kids to join up, then the death spiral is accelerated even more. If you think folks are pissed now, just wait.
