Insulin is a solved problem, in first-world countries the sale price is fixed and there's public healthcare. But in America you are supposed to take "personal responsibility" for your own health and biohack your way ouf of type 1 diabetes?! Srsly? This s a political, not a scientific problem. Call your congresscritter.
The question is why no one is calling for price controls for other products that are produced in a relatively free market. Then ask yourself whats different about the market for insulin that prevents price competition.
Using "fixed" prices to control costs is like using "fixed" thermostat readings to control global warming.
