I would say it's a natural thing: our biases are mainly a creation of our subconscious, multigenerational experience starting from prehistoric times, our instincts. And before industrial era and before long-range maritime trade started, world has been pretty much a zero-sum place, so perceiving everything as zero-sum is "natural" to us. Come to think about it, there must be a class of businesses based on this bias, it must be one of the hardest for people to overcome (just as it is hard to overcome lure of sexualized ads: that too, is an instinct, requiring too much conscious power to reject, especially when seeing it casually).
