Do the math.
People who get subsidies, or go onto Medicaid (like Donna and her daughter), will do quite well.
The people who get shafted on their premiums and taxes to pay for these "winners" will not.
By definition, there have to be fewer of the former than the latter to avoid permanent deficits in the system. That's the bottom line. You don't need to wait for more numbers.
The letter Donna got from her insurance company letter directed her to their web page. The page practically rubs your nose in the Washington HealthPlanFinder system, the state connection to Obamacare. This is not "hiding information."
Either Donna is a bit stupid, or a shill. So far a lot of these "Obamacare is swell" types have turned out to be shills.
