Robert Heinlein is not overly concerned with subtlety. Perhaps fearful of some particularly dense reader missing his unmitigated support of the military, big government and capital punishment, Heinlein places only the thinnest of sci-fi veils over his long-winded political monologues. This does not make it a bad read – the plot is still compelling – but when I reach the scenes of History and Moral Philosophy classes, I do want to throw something at him, as roseblack says. This future world in which Johnny Rico operates has indeed been radically altered.
