Mass famines are really not the kind of thing a capitalist should bring up as an attack on an economic system, given the examples of Ireland and India.
“Communist societies had the two most major ones though.” - people who usually know nothing of communism
There’s also the infamous American Dustbowl, but capitalism never has to answer for its own famines. It’s kind of like how communists constantly get the excesses of Stalin and Mao thrown in their faces, while the horrors of poverty and wage labor and deliberate inequality are a thing capitalists are never asked to answer for.
Or, to be a bit more on the nose, here’s Mark Twain on the Terror.
Mark Twain wrote:
“There were two ‘Reigns of Terror’, if we could but remember and consider it; the one wrought murder in hot passions, the other in heartless cold blood; the one lasted mere months, the other had lasted a thousand years; the one inflicted death upon a thousand persons, the other upon a hundred million; but our shudders are all for the “horrors of the… momentary Terror, so to speak; whereas, what is the horror of swift death by the axe compared with lifelong death from hunger, cold, insult, cruelty and heartbreak? A city cemetery could contain the coffins filled by that brief terror that we have all been so diligently taught to shiver at and mourn over; but all France could hardly contain the coffins filled by that older and real Terror - that unspeakable bitter and awful Terror which none of us has been taught to see in its vastness or pity as it deserves.”
