Wine and beer are the enemies of wisdom. Well, to sober people, at least. Drunk people think they're brilliant. Moral: if there's drinking involved, make sure you join in.
Making the king angry is a sin. Hmm... that's a mighty convenient way to keep one's flock in line. Lazy people don't like to plow when it's cold. So ignoring all that lovely stuff in earlier books about allowing them to glean the fields after the harvest, now we're supposed to let them beg. God, this whole book is written like a Republican manifesto against the poor. Next thing you know, it'll be whining about the need for cutting corporate taxes.
All kings have to do to decide if a person is good or bad is look at them, which, again, is awfully handy when your constituents get stroppy.
