Ruling class: "We already rule the world, that tech is going to fuck up the bag. Guards, stab him."
Merchant: "I have 100 ships currently hauling from 10,000 farms, and you're telling me anyone can make it anywhere? If this catches on, Ill be ruined. Stabbing you is basically self-defense"
Peasent class: "Wait so the lord will only need 1/10th us to do ?? Fuck that shit, you want 90% of us to get drafted into some dumb war? We gotta stab him before the lord finds out."
