I don't agree; he was just stating a fact about power. When you get down to it, moral and legal codes aren't real, they're just arbitrary concepts people agree to abide by. Classical Greeks thought it was pointless to attempt to legislate for all situations and had a notion of 'virtue ethics' - that what a sufficiently virtuous person does must of necessity be virtuous/ In our own time, it's plain that sufficient power does in fact put people above the law and that's a reality we have to deal with whether we want to or not. Rule of law is only as good as the amount of respect people have for the law, and law as an institution has been on a decline in the west and in the US in particular, because so much of it is so obviously for sale to the highest bidder.
