Yes, capitalism as a formal economic system is recent but the behaviours it’s built on aren’t. Competition, territorial control, hoarding for security, unequal outcomes all of these exist across nature (including humans). Lions fight for dominance, trees compete for sunlight, squirrels hoard food. Resource competition is older than any ideology.

Communism, on the other hand, assumes sustained large scale human cooperation without hierarchy, which has never existed stably either outside small tribes where scarcity was low and populations small. Scaling that to millions is where it collapses.

I’m not defending status quo. I support regulated capitalism with social welfare (centre-left). Capitalism needs checks, not abolition. Meanwhile Communism needs human behaviour to fundamentally change.

One system builds on instinct and incentives and the other demands we override them entirely.

That’s the difference in feasibility.
