Well then wouldn't you say that people are the root of all evil, or perhaps scarcity for providing the instinct for greed? Scarcity results from living on a finite planet, there's no helping scarcity. Walking that to its logical conclusion, evil doesn't really exist. Some people are more self-serving than others. Trump could have made more money collecting interest, but chose instead to employ tens of thousands of people. Hillary Clinton is worth well over 100 millon (possibly billions with the foundation) dollars from a career as a "civil servant". I think Clinton is far more self-serving than Trump in that sense.
