Therefore US drug policy is bad.Well, from the (very cynic) view of an armchair psychologist, one of the possible consequences of a child losing their parents can be a subconscious feeling of inferiority, of not being wanted, of not being good enough, ever. Depending on "temperament" and character, this kid could suffer from severe depressions all their life and never achieve anything or they could react to this by starting to heavily over-compensate and trying to be very successful and powerful. So, yes, if you want to put it like that... scarring an unsuspecting kid for life like this might just ultimately yield you another CEO hero, however unlikely.
Work, power and success can be a very potent drug and/or replacement. Not all motivations in life are positive, nourishing and healthy. Even very self-destructive tendencies could at the same time yield you tremendous (outside visible) "success", status and money.
