But the observable facts are that in the generics market there are only a few players, and profits in the generics market are low. If the economic theory can't explain that, it's the theory that is wrong.
What's happening inside the U.S. is harder to model. The patented versions of insulin are somewhat better than the generic ones. There might be insufficient incentives for people with health insurance to prefer the slightly inferior but much cheaper version. That leaves only those without insurance to pay for the generic, and that's not much of a market. As a biologic, insulin is expensive to make even the generic versions. And people who have no insurance probably have little ability to afford it.
And this included something as simple as saline.
Manufacturing IV solutions is something that requires a clean room laboratory, with its own set of stringent requirements and doing it cost-efficient means doing it at scale.
Actually, don't, you'll probably injure yourself.

A hybrid approach in the US has been fairly useful for orphan indications and, somewhat differently for vaccines, but of course jerks found ways to exploit that too. Still it points to a possibility.
But I favor a single utility making some small-molecule and biologic underserved drugs because of the economy of scale it could bring. A small NIH facility in some otherwise underserved part of the country could make a big difference at a relatively low cost.
Would you like to re-think whether it's possible to invent and develop important new things without immediate profit motive?
Government funding isn’t an alternative to the market; it’s a different kind of market partipant. Government funding competes with private investment, and government agencies compete with the private sector for talant, etc.
It's not that bad. Brewers developed the knowledge how to work with microorganisms centuries ago. Most antibiotics are biologics, and they are dirt-cheap. Insulin isn't monoclonal antibodies, it's grown in bacteria, in the simplest expression system, and how to isolate it from the fermentation batch is well-understood and involves no problematic steps.
I agree that France or Brazil are better candidates for this approach.
