Another thought. Also remember that for every blockbuster drug that a pharma company comes out with that gets through the FDA and they make billions off of, they have 20 or more that they invested the same amount of money in during the same period, that didn't pan out into anything. Total loss of investment capital and time. I spent my life in this industry. They have zilliions of failures that each can cost hundreds of millions of dollars. I'm not defending all of their practices, just offering a perspective. I hate how they gouge Medicare full price, when they discount to insurance companies for the same drug. That kinda crap has to stop. But they do indeed advance much of our scientific knowledge that ends up in the public domain through their many many failures and successes. It all gets published in pieces before they have the total picture to make a working drug, little bits of understanding that can also be used to stimulate other ideas and solutions by third parties.
