Remember when the White House explained that the huge hikes in Year 2 were due to all of the uninsured people suddenly having access to health insurance and that it would settle down? Why are we having these large increases in year 3?
Very simple actually. When you give people instance access to health insurance pretty much anytime they want without any pre-existing condition limitations, your claims experience is going to be awful.
