Here's a nifty article on the fight against malaria. The story makes me think about the pressures on drug companies. They are supposed to maximize shareholder value, make sure their drugs are safe for everyone (or face huge lawsuits if even one person dies out of millions of users), and find new drugs to save lives under increasingly harsh and expensive regulations. In this instance they are being told not to sell a certain very effective malaria drug because the use of it is slowly making the disease resistant, yet if they do stop selling it, shortsighted idiots who already hate drug companies because they don't give away drugs for free will start protesting about how cold and heartless they are. What's a big business supposed to do?
