When you talk about “slaves” to modern American kids, they automatically think “black slaves”. They know what they’re supposed to think and that’s what they’ll think. The only thing this lesson is designed to normalize is a hatred of the America that used to exist, so that they’ll cheer the New America.
When the New Order takes over and makes slaves of us all, they won’t call us slaves. They’ll have a nice, feel-good term for it, so preparing kids to think of themselves as slaves (as you believe) is going to be pointless because no one is ever going to call them “slave”. They’ll probably be called “Comrade” or even “Citizen” as they are being shippped off to work in the collective farm or mine.
And isn't it great they will have learned to do the math for how many slaves will be needed. Some of them will be our managers and some of their friends will be slaves.
I think we're both speaking the same result and just wording it a bit differently.
