Solving the prescription drug price problem

Farm the problem out to WalMart, and make it a logistics exercise.  Like a gold delivery service, the on line protocols automatically re-distribute inventory over the net to increase liquidity.  he government is limited in responsibility to making good buys when the opportunity comes, and feed the network.   Another case where TOE works, what you need is a drug exchange protocol, an key secure system where two way exchanges across network nodes is facilitated. Then the network is adiabatic, and that is a key bargaining point against drug suppliers.

Make it a public protocol, make it simple exchanges.  Then here the encryption and key management pros so the drug pros can track their activities. The government only has one obligation, find sources of proper quantity, and then e squeeze them on price.  Separate the drug network entirely from any other medical insurance program, instead treat this as a frontier logistics management problem. Separate government budget, separate government funding.
