Because of the exchanges are coming in lower than previous market costs, plus this competition is massive because of so much money that's at stake whereas companies desperately want a piece of that action. Also, most of volume of the ACA actually deals with cost containment.
According, the recent CBO report is that they expect a reduction in overall costs, and if my memory is correct, it's by 13% within the next 4 years, which was mentioned by the director of the CBO in Congressional testimony a couple of days ago. However, if it turns out that my "memory" is somewhat off, I'll deny ever saying this.
I have not seen the most recent figures on this as I've not seen any released over the last few months, probably because we're in the midst of the sign-up period. What I did mention, however, was based on actual stats and not estimations.
We shall see about their prognostications.
But note that the CBO also predicts the loss of the equivalent of millions
of jobs due to Obamacare. Is this cost factored into their calculations?
It actually doesn't say that and, as a matter of fact, the director said the study shows an actually increase in the number of jobs in the long run. As far as the various components of their analysis, I can't speak to that.
If you Google it, I assume you can find his testimony to Congress made a couple of days ago, parts of which I watched on tape.
