Someone actually did the math to figure out how many people died from capitalism, and if you check the stats, he's correct. The figure doesn't even count deaths from wars, suicides, and working conditions.

The World Health Organization estimates that 3.575 million people die from lack of clean water, and that 1.5 million people die from vaccinable diseases every year. Mercy Corps estimates that nine million people die from hunger every year. By summing these deaths, it can be concluded that capitalism kills approximately 14 million people per year.
