It seems like you are completely missing the point. This has little to do with economic inequality. The issue is not that this guy had a random product and raised its price. If this had been a car or an iPhone, we could not have cared less if he had been "greedy" and selling it for $1M/piece. The issue is that this is medicine we're talking about. People don't view healthcare and medicine like they view ordinary services and products. Many people (perhaps not you) have a much higher threshold for what kind of practice is moral/ethical/acceptable in medicine. That's why even in the middle of a battlefield people think it is inhumane to prevent doctors from treating injured soldiers, the war be damned. There is more to humanity than money.
