"Policy makers apparently failed to ask the important question: How could this happen in a free-market economy? That would have steered them to the giant purchasing organizations that control the procurement of up to $300 billion in drugs, devices and supplies annually for some 5,000 health care facilities. These cartels have undermined the laws of supply and demand."
I'm pretty sure the question is meant to be a question you ask to lead you to where the free market is indeed being broken, not a claim that we have a free market.
This is solid logic; if the free market can do anything, it's match supply and demand via price signals. (If you're having a political reaction to that statement, I mean this in a simple microeconomics sense; it is indeed what free markets do.) In the absence of raw material problems, pervasive shortages are effectively proof that somewhere in the system, someone's fixing prices to below production costs. Sounds like they might be combining that with some good ol' fashioned corruption.
(This is why I'm a "libertarian" and not an "anarchist"; the free market needs defenders, because as beautiful as the theory is, in the real world, stuff like this happens, and it needs to be stopped by somebody with the power to stop it.)
