Neven Mrgan takes a prescription drug called Cuprimine. Without it, he would slowly die from liver disease. Unfortunately, the price of Cuprimine has gone from $400-$1,700/month to $44,000/month. Curprimine is made by Valeant Pharmaceuticals, run by billionaire J. Michael Pearson. He's stepping down, not because he jacked up the price of Cuprimine and other medications, but because the company's misstated earnings hurt its stock value.
