I'll admit to being a cynical asshole but just dunk on them. Don't even bother to engage with this sort of shit without an audience, you're not gonna change anyone's mind who thinks there is an economic benefit to this horseshit, shit's all just made up numbers to paint your arguement as scientific.

Just call them willful serfs or peasants or something. Really appeal to the individualism, maybe you'll change someone elses mind when they can't square the difference between being a rational totally selfmade individual in favor of supporting a fucking monarchy.
