Like most numbers that come out of government, it takes a bit of creative license. Both major parties have mastered this deception. The real question is... Are we better off now that this law is in place? To which I have to think, probably not.
"Probably not?" You're going to have to explain that one. Maybe some people are worse off, but millions are MUCH better off by not being denied health care for pre-existing conditions, being able to stay on their parent's healthcare plans, etc.
Granted, this IS a right-wing change to health insurance (from the previous generation of right-wingers, not the Tea Party wacko set we have now). This is a gimme to health care insurers, with no single payer, etc. It's a single step, but it's a good one until the Tea Party flames out and we can get back to having a somewhat functional Congress again. That's going to be a long time in coming, I suspect, so for now, it seems as good as we're going to get.
