Faith in pharmaceutical companies

I had an interesting conversation with people who have a very bad opinion of pharmaceutical companies. They were convinced that they were a company that wiped out the human population. They didn't even want to hear my opinion. That's why I took the liberty of writing it here. As far as I know from history, without vaccines and medicines, man could hardly prolong life. I am not an advocate or a spokesperson. But my opinion is that the word medicine means to cure. Regardless of whether it is an herb or a tea made from different herbs or minerals, aren't medicines made from them? It was chemistry. Aren't these ingredients from our planet? Isn't the research done based on what can stop the causative bacteria? A drug had to be discovered for a minimum of seven years. Not in a year. Don't we live in the era of fast communications and fast computers? It's one thing to discover the formula; it's another thing to produce the drug itself. Don't the big companies have research centers? Don't they get government subsidies? Which politicians would vote money to cut their constituents? What company would want to destroy its customers? There is no logic. I admit that if a drug helps one, it can harm another. Everyone organizes the reception differently, and therefore there are opportunities for problems. But, in general, not believing them is insulting. However, the hope is in this. Until we get into a situation, but with climate change and the melting of the ice, what diseases will befall us? Hygiene is the number-one factor. Healthy food is number two. Sports and maintaining the body are number three. But medicines will always be a necessary spare part of many people's lives. Let's hope we don't have to use them.
