I think if you want to pin a blame on something it needs to have happened as a direct result of that thing. A factory burns down in China kills a bunch of people inside. Is that because Communism? Or just an accidental tragedy? Seems like fire happens whether you are capitalist or not. So I wouldn't count industrial accidents to normally be so.
Now, a failed policy of centralized economics that results in mass starvation? That's because communism. Someone starves because they couldn't afford food? Well then that would be capitalism -- but because one happens doesn't mean it wouldn't happen in the other. Someone can't afford food in a capitalist economy, doesn't mean they'd get food in a communist one necessary if the problem was a genuine supply-side shortage.
Take china for example, it did not have food supply issues prior to the great leap ahead -- those deaths happened BECAUSE of it, plain and simple.
@Galena @mewmew @sylveon This thread is a indictment of public education. For shame.
Regarding deaths, its all pretty well documented. There is some controversy, but your free decide on your own.

Second, Capitalism, or more specifically, Free Markets are nothing more than private property and voluntary trade/interaction. We've got plenty of documentation on the mass killings of Communist countries to get those staggeringly high death tolls, but regarding claims like "Capitalism has killed more" I've never seen a source. Go find one and I'll read it.
We've got plenty of documentation to make it clear that Capitalism has brought more people out of poverty than anything else in history, though.
Thirdly, nothing about capitalism or free markets prevents a government from being corrupt. Anytime you have a government of any kind, you get corruption. The only grace in this area where Capitalist economies have a boost is that they have less centralized control. That doesn't prevent them from rolling 3rd world governments in south america. Only way to get rid of that is to vastly limit state power.
