That won't happen, the government is the one preventing it because of the patent restrictions. If the patents were limited then companies would spring up instantly to manufacture it cheaply.
They're also the ones holding back generics to a dramatic degree via the FDA approval process, which would stop a biosimilar insulin from making it through. The government has entirely rigged the game. The statistical change in approvals is so dramatic and inverted, as to be implausible to be anything but intentional fraud on the part of the FDA. (why fraud you might ask? deceit for monetary gain: user fees paid by big pharma)
