I can't read the article, it's behind a paywall. But from the comments I get that people don't truly understand that there isn't just one thing called 'insulin' that is universally the same. As the husband of a type-1 diabetic who has been on $25 Walmart generic insulin and $1000 name-brand insulin (we have insurance, obviously we don't pay that amount), I can tell you they are not the same. For my wife, she never has unexpected highs/lows on the more expensive insulin. So, sure, non-generic insulin is probably more expensive than it should be. But there was serious research and development done to make these better insulins, and thankfully someone did because they can make life just that easier to manage for a type-1 diabetic.
