Obamacare was indeed sold to the public with the promise of containing costs, but I think it was naive to expect it to fully deliver on that promise, if the players (i.e. doctors, hospitals, Drug companies and Insurers) were not really forced to change their ways.  It is still a fee based system and it is overused/abused.  

I can understand why Americans do not want to go to a single payer system, they hear the limits that will be imposed on them and immediately state their opposition to it.  As more and more cost is passed onto employees this attitude may begin to change.
