This is a case where I see both sides of the problem.
A member of Big Pharma gets a vaccine that will help us to resist the current strain of the flu. But one factor regarding that beast is that we haven't found something that resists ALL flu because as it turns out, the flue virus evolves continuously. In an attempt to target a given strain of flu, we make a specific vaccine that targets something about the structure of the beastie, only to find out that next year the vaccine we just developed won't selectively target the new kid on the block. And to make a generic vaccine faces the same issue, except that whatever escapes the generic vaccine would be a nasty little bugger that really COULD reach pandemic levels. Further, we have to remember that viruses are made of the same sorts of things that WE are made of.
Look at some of the commercials for weight-loss or anti-depression drugs and listen to the litany of side-effects that occur because the drug, in order to do its thing, might accidentally do a worse thing elsewhere if you happen to be sensitive to it. That's why I can't take the semaglutide class of drugs. It has side effects that stress the liver, but my liver is not the healthiest part of me. Comedian Jeff Foxworthy has a spot in one of his comedy routines about a drug to eliminate some minor condition, but he has a literal A-to-Z list of diseases and conditions that are side-effects of taking his hypothetical cure for the minor condition. The side effects include halitosis, scoliosis, mononucleosis, and a couple of other osis conditions... but the list keeps on going. I laughed at it. Then about a year after I first heard the spot, I heard a legitimate drug ad where they couldn't use a 15-second spot because the list of known side-effects was over 30 seconds long... and one of the lines was "...If you or a loved one taking 'mumblefratz powder' experience numbness, dizziness, or death, discontinue taking it and call your doctor." I kid you not, it really said to stop using the drug if you experience a list of effects including death. Well, I guarantee that when it comes to taking drugs, if I die, I guarantee I will stop taking that stuff right away! But I digress...
When we talk about business, we talk about how businesses need to stay agile to meet the demands of a constantly changing world. We develop new products, new technologies, new ideas - because that adaptability to changing needs is how businesses survive. Where do you think we got that adaptability from? Bacteria and viruses that adapt to survive.
Big Pharma has made some business decisions regarding pricing that I think are unconscionable. But that doesn't mean that they are 100% scum. They are a useful business with bad practices. Now if we could just separate the good from the bad...
