i would claim the opposite relationship. the period that modern democracy sprang from was an era where the emergence of industrial technologies increasingly eroded the monopoly of force held by the aristocracy. industrialization resulted in the democratization of force, because weapons became ever cheaper to produce and easier to use, forcing the aristocracy to first parley with merchants, and ultimately with the peasants. the advent of the mass-produced automatic infantry rifle in the mid-20th century marks the height of this democratization, where even a peasant child in the ricepaddy could strike down the helicopter or strike aircraft.
it was the emergence of high technology that has reversed the balance of power. those who control high technology have disproportionately more lethality than those who don't. feudalism re-asserts itself because it can.
