The way to break down a two tier pricing system because of a monopsony in one place but not another, is with trade. Simple really. But what is really needed is the Torie plan, which involves the drug companies being proscribed from charging higher prices in the US, except to the extent attributed to cost savings from volume sales.

There's no need to ban differential pricing when allowing free trade will do the job just as handily. Consumers will, acting by the unbribeable, unbreakable, uncooptable laws of economics, use arbitrage to break down the pricing differentials. When that happens we will find that, just as in the market for computer chips, the era of high-tech drug research and development will begin for real.

Not when the government monopsony buyers don't resell.
