I dont think it's a quantity issue. I think it's a ruse, and a precursor to a new, more expensive treatment. Or just a more expensive treatment.
The article you posted from CNN cited future statistics that
dont exist. It was an IF / THEN scenario, set 12 YEARS in the Future, meant to scare you into submission-- could be more invasive insurance requirements to get a "discount" (that is, to avoid a penalty charge) on your premium.
Have a look, yourself-- here's another
article.
And from another:
... more than 90 percent of privately insured patients with Type 2 diabetes in America are prescribed the
latest and costliest versions of insulin.
But it’s not clear that these newer formulations are significant improvements on older ones, the researchers wrote. “The data are not definitive on whether insulin analogues being used today are safer or more effective for most patients with type 2 diabetes than human insulins used widely in the 1990s, for which the main
patents have expired.”
LINK. This is a good article btw on the history of the drug, whose original makers refused to patent. Because it's wrong.

The US (citizen) pays more than other countries for drugs. And drug makers endlessly try to renew patents to keep the profits HIGH. I have a deep, personal loathing of the pharmaceutical industry. The European and and Asian markets have safety warnings and mandates that arent required here. That's fundamentally wrong, and countless people suffer (and die) needlessly because of that.
