That whole dumb trope which amounts to projecting your desires to kill the upper classes to bring about a utopia onto "the other" again? It is a projection-propaganda meme accusing the enemy of planning violence to justify your own, mixed with trying to recruit a revolution they feel entitled to.

Even a complete cynical Machivellian with no morals would have better uses for masses post automation. Even keeping them on the dole just to have a conscriptible population to do the massive amounts of logistical gruntwork would make sense. Populations are a variable in military power, even as war machines mean fewer boots on the front lines and more in the logistical support. Only a complete idiot would throw a large population advantage away.
