Their formula was being wealthy enough to float above war, upheaval, regime change and so on. If they were wealthy enough, they probably triggered some of that and capitalized on war profiteering.
I think it's the drive-by, reflexive assignment of guilt, while knowing nothing of the circumstances.
This strikes me as the opposite of thinking. What you said might be true, it might not, what have you added to the world?
"This is probably referring to the rothschilds based on (link to historical information). It's reasonable to extrapolate that they were war profiteers based on (reasoning)"
Then I think it really could have added some insight into the world instead of being like the drive-by ignorance the parent comment refers to.
