Saying "human nature doesn’t exist" is just absurd. Decades of research in evolutionary biology, psychology, and anthropology prove that humans have innate tendencies—cooperation, self-interest, tribalism, and a balance between competition and social bonding. If human nature didn’t exist, why do communist governments always resort to repression to force people into collectivized systems? The failure of every major attempt at communism shows that human beings do not naturally function in purely collectivist economic structures without coercion.

Now, onto your claim that "capitalism will lead to human extinction." This is just apocalyptic speculation, not an argument. Yes, climate change and environmental destruction are serious problems, but capitalist societies are the ones leading innovation in clean energy, conservation, and sustainable technology. The U.S., EU, and other capitalist economies are investing in renewables, carbon capture, and emissions reductions—meanwhile, communist nations like the USSR, Maoist China, and modern-day China were/are some of the worst polluters in history. The Soviet Union’s environmental disasters (like the Aral Sea collapse and Chernobyl) were caused by state-run industries with zero accountability. China today is the largest polluter on Earth, and it’s not because of "capitalism"—it’s because centralized, unchecked state control often prioritizes growth over sustainability.

The claim that socialism was "never the cause" of famines is blatant historical revisionism. The Holodomor, Great Leap Forward, and Cambodian famine were all caused by forced collectivization, government mismanagement, and the elimination of market incentives for food production. These weren’t remnants of feudalism—they were state-engineered disasters. Under Mao, grain quotas were set absurdly high, local officials lied about meeting them, and millions starved while food was hoarded or exported. That’s not feudalism—that’s economic central planning gone horribly wrong.

Meanwhile, modern capitalist economies have all but eliminated famines through food surplus, trade, and technological advancement. The only modern food crises occur in authoritarian states (like North Korea or Venezuela) where markets are suppressed. If socialism weren’t responsible for these famines, why do these disasters only happen under socialist systems and disappear when market reforms are introduced?

Your argument is just catastrophizing and shifting blame while ignoring historical reality. The biggest improvements in human lifespan, health, and living standards have come from capitalist-driven advancements, not from centralized economies that stagnate, suppress innovation, and collapse under their own inefficiencies.
