Traditional insulin is cheap in the US. The price has not changed in a decade. Nobody wants it, it is a product of last resort.
Modern insulin is protected by moats, two of which are intellectual property and regulatory approval. Modern insulin being cheaper in other countries is because they are not following the same trade and approval laws. The way to match abroad prices would be to change protections and approvals, the latter of which is and has been happening over the last five years.
