Note that those markup figures are based on production cost, excluding capital investment. Lilly is profitable, but not any more profitable than Google or Facebook or Apple.
Making critical products less profitable than less critical ones is often contrary to “the interests of the people.” It drives investment from stuff like new pharmaceuticals to stuff like dating apps.
Insulin is actually a perfect example of that. The first generation insulins now are relatively cheap. The “insulin” we’re talking about here are second-generation insulin analogs, which are easier to administer and help better control blood sugar levels. We are at the tail end of the patents on those and we are already starting to see generic insulin analogs being made at Wal-Mart.
You have to think about the system in terms of how humans work and their motivations. Brilliant people who can make new, better insulin aren’t born any more altruistic than the people whose talents are better suited to coming up with new advertising algorithms. They want to make a bunch of money from their work. If you make it so that smart people can make more money doing an ad-tech startup rather than a bio-tech startup, that’s what they’ll do.
