WTF? You are the product of your genetics AND your life experience. If anything, I've always felt that the latter, not the former, is the dominant factor. Granted, there are other biological factors apart from genetics that may disadvantage you at birth (e.g. exposure to alcohol / drugs / tobacco before birth). But to suggest that genetics is "most of the story" in determining your lifelong socioeconomic success, I find to be absurd.
