The market simply cannot correct for this. It's just not possible. As fewer people can afford care, prices will go up to offset lost profit. The only organic correction that can happen is if so many people die that the entire economy collapses.
So yes, we'll see a decrease in hiring, a decrease in the number of insured and/or healthy workers, and absolutely nothing will change. The public simply cannot squeeze insurance into lowering prices, nor can businesses. Only legislation can fix this problem.
But since that seems to be ever more unlikely, the best solution is probably for the people to storm the insurance companies and put the CEOs on pikes for all of the death and destruction they've inflicted on our entire society. Democracy has utterly failed us and the only reasonable option left is incredible violence. That's the sad, sorry state that american society is left in today.
