Let me be clear,
I mean non "natural" deaths, and am including stuff like the failure to counteract malaria due to lack of profit motive, etc etc etc.
Real question, is capitalism the deadliest human invention of all time?
this will probably come down to where you draw the line between capitalism and imperialism, but I'd argue they've been largely once unified force since at least the 1920s
This is the thing, capitalism has brought a massive increase of our productive capabilities while it was still a progressive system, which has lead to many advances like modern medicine. In imperialism though we're also seeing the exact opposite, like scientific progress in medicine being held back by patents because of monopolies competing with each other.
