There is more science available, big data, ability to manufacture practically anything for not a lot of money, I love the fact I can hop online and read studies from a journal that published last week. Couldn't do that in the 90's. Increasingly seeing a reversal or abandonment of medical theories as new studies offer new insights and present new theories. So the trend up to WW1 was to use chemicals found in us to treat us, between WW1 and WW2, patented medicine started to appear and this is how big pharma developed. Problem is, in some cases, patented medicine is too alien to the human body, its not evolved enough and so it presents new challenges or problems, depending on your POV. I'm not saying its perfect today, but the explosion in knowledge over the last 30years has been close to exponential, roughly inline with the silicon chip.
