Except for the millions of people who die each year from all of the toxic waste companies dump into the environment in their pursuit of ever increasing profit margins, the millions of people who die because they cannot afford medical care many of which related to the previous point, the thousands of people who die each year because the military industrial complexes around the world needs to coerce their governments into endless war to secure their own on-going existence, etc.Capitalism has never killed anyone.
Countless people are going to die regardless of what economic system you put in place so long as you have corrupt leadership looking to hoard power and wealth for themselves and their circles.
