What’s important to remember is that this is not how Obamacare was supposed to work. The Congressional Budget Office, in its original estimates, predicted that the vast majority of the people eligible for subsidies on the exchanges would be previously uninsured individuals.
Instead, the vast majority are previously insured people, many of whom are getting a better deal on the exchanges because they either qualify for subsidies, or because they’re older individuals who benefit from the law’s steep rate hikes on the young....
The bottom line is this: there are a lot of numbers flying around out there about how many people are benefiting from Obamacare. A big part of the reason is political; advocates of the law want to claim that so many millions of people are dependent on the law for coverage, that it will be difficult to repeal.
"American taxpayers have forked over $2 trillion to uproot an existing system with which most Americans were satisfied. If only a fraction of the law’s “newly” enrolled previously lacked coverage, how many Americans will consider the broader expensive disruption to have been worth it?"
