And again I'll come back to it and say that's great for you, but I don't think that's reality for most people. Health care costs are going up on average 3-4% a year. It stands to reason that premiums will as well (or dedictibles would be increased) unless your employer has chosen to eat the cost increases or has found increased efficiencies every year. What you're saying is you have zero extra trips to the doctor between yourself, a wife, and two kids and have had zero premium increases over that time. That's a nice situation to be in but I suspect a rare one.
Getting back to daxe's point, lets break it down. $480 a year higher premium. If he's in Mass, but not knowing who he's covering, lets say he's paying 6K or so a year for his insurance. Applying the 3-4% typical cost increase, he'd be paying half that $480 anyway regardless of the ACA. So, a $240 increase, or 20 bucks a month for presumably better insurance (no annual limit of something really bad happens, lower deductible, etc).
As I often say to conservative whiners, if 20 bucks extra a month is the biggest problem you have in life, consider yourself lucky.
