Hmm… and people always object that I shouldn’t try to figure out what Heinlein felt from his stories.
This feels not all that different from the political system in Starship Troopers (and defended in Expanded Universe), only with the added nasty fillip that not only ought you to earn your right to voting citizenship through Service, but that the State need not defend anyone who doesn’t support it against assault. Heinlein musta been in a rotten mood that day.
