Trope-a-Day: Arranged Marriage
Arranged Marriage: Despite the plethora of old families, noble houses, and other outbreaks of hereditarianism, strongly averted in the Empire. Partly because at least these strong individualist-propertarians can understand each other well enough to grasp the ethical problems here (see Blue and Orange Morality), and partly because they definitely understand each other well enough to realize that Nothing But Stabbings Ensues.
Doesn’t stop the matchmakers from throwing people at each other and seeing if they stick, often for similar purposes, but they know perfectly well that they can’t even hope to require.
