Pharma investors have a solid position and are already racking big profits from the continuous model of insulin treatments. A cure would be a detriment to their profits, so it's not something they're interested in funding.

No investor nowadays thinks a one-time-payment product is worthwhile. We're already way past that.

This isn't to mention that if you were an investor who decided you wanted to go ahainst that, that the other mega corporations (with more funds than most of those 5% individuals) wouldn't engage in anti competitive practices to shut you down. Many companies had good products but still ultimately failed. I mean hell, the boeing events have shown us the lengths a corporation is willing to go to protect its profits, and that's just what we heard of.

Unfortunately capitalism does not allow innovation to flourish like many of us were taught to believe.
