It’s true that capitalists and other parasitic elites often use violence when the people over whom they rule try to shake off that rule, I agree. For most of history, it was the oppressed rather than the oppressors who died in these situations, though.
As Mark Twain pointed out in “A Connecticut Yankee in King Arthur's Court,” we often bemoan the violence of revolution, but in reality there were two Reigns of Terrors in France—that of the fanatical elements of the French Revolution, but also centuries of constant, daily, grinding violence by the aristocracy against the peasantry that we somehow don’t look on with the same disgust.
