Wow, tell me how you really feel
Ok but tbh a similar case can be made about retail chains. Some people would say its evolution while others would say it destroyed the previous model. I agree that PBM's were created for something else and ended up doing something else instead.
Now I agree with you that a single payer would be the best way to deliver health care services in this country, but I like single payer because of different reasons (access). Now, single payer does not mean there would be no red tape.. case and point- Medicare plans. I have some reservations with the drug companies not making a huge profit because it is that profit that drives innovation.
Managed care should be on the decline with the passing of ACA. ACO's might be the new "thing". Managed care was a great idea at the time of its conception but fee-for-service has to go and it seems like its on the way out in favor of concierge medicine.
