During the trial it was revealed that McDonald’s knew that heating their coffee to this temperature would be dangerous, but they did it anyways because it would save them money. When you serve coffee that is too hot to drink, it will take much longer for a person to drink their coffee, which means that McDonald’s will not have to give out as many free refills of coffee. This policy by the fast food chain is the reason the jury awarded $2.7 million dollars in punitive damages in the McDonald's hot coffee case. Punitive damages are meant to punish the defendant for their inappropriate business practice.
Capitalism opens an avenue for greed to be used for the benefit of the many, whereas any other form of resource distribution has no place for greed and as such no place for the greedy. At that point it becomes the same kind of discussion as the prohibition discussion. Do you ban it or do you allow and regulate it. Banning greed won't make it go away, it will only force it into hiding and to undermine the current system. Capitalism forces greed to the surface, at which point people can have a discussion about how much greed should be permitted.
