If a person wants more power so they can enjoy such "fruits" (more money, control over other people, more pleasures, ...), then they will support people who exemplify those negative characteristics. Believe me when I say that despots don't gain power without significant support from other low-virue folks. That is really the story of human history.
But, no, it is each person's personal responsibility to seek and attain some measure of spiritual growth, with humility, honesty, perseverance, and study. Just like a CEO with bad personality traits will cause negative downstream effects, any individual with those traits will poison the teams they work on or whose work they affect.
As to competition among humans, that is just our common delusion, whereby we are fearfully convinced that we are merely mammals competing for scarce resources, instead of human beings who are capable of cooperation, generosity, compassion, and selfless service for the benefit of the whole, including future generations.
What we are witnessing across the Earth's societies is nothing less than the apotheosis of the masses' majorities exercising their free will to choose ignorance over wisdom in how we treat each other and what we will allow our organizations (such as corps and govts) to produce. A human life committed to selfish competition against other groups is a life wasted on mammalian idiocy, and always results in degradation of the whole.
Why are we not all humanitarians? Because most people reject our highest possible ideals, attitudes, and behaviors. Their reasons are numerous, but none hold any weight, for none will bring them peace and happiness, because only by making other people happy can we be happy. And we can only make other people happy by giving of our selves selflessly and compassionately.
