The numbers on this chart are nonsense.
A very quick internet search shows that approximately 10 million indigenous people existed in the United States prior to European involvement (https://worldpopulationreview.com/state-rankings/native-american-population). How did 50 million die?
The estimated number of African Americans who died from the slave trade is estimated between 1 and 2 million (https://www.clrn.org/how-many-slaves-died-in-american-history/).
The Indonesian civil war casualties are estimated just over 100,000. (https://en.m.wikipedia.org/wiki/Indonesian_National_Revolution). And the United States wasn’t even involved in that one.
And those are just the three I checked. My guess is every single number on this chart is wrong. I agree that capitalism sucks and has killed lots of people, but pushing nonsense doesn’t help anything. You could put the real numbers on there and still get the point across.
